We can work on Experiment; A Volumetric Analysis

• To prepare and standardize a sodium hydroxide solution
• To determine the molar concentration of a strong acid
The following techniques are used in the Experimental Procedure:
Experiment 9 127
Primary standard: a substance that
has a known high degree of purity, a
relatively large molar mass, is
nonhygroscopic, and reacts in a
predictable way
Standard solution: a solution having a
very well known concentration of a
solute
A titrimetric analysis requires the careful addition of titrant.
Objectives
Techniques
A chemical analysis that is performed primarily with the aid of volumetric glassware (e.g., Introduction
pipets, burets, volumetric asks) is called a volumetric analysis. For a volumetric analysis
procedure, a known quantity or a carefully measured amount of one substance reacts with
a to-be-determined amount of another substance with the reaction occurring in aqueous
solution. The volumes of all solutions are carefully measured with volumetric glassware.
The known amount of the substance for an analysis is generally measured and
available in two ways:

  1. As a primary standard—An accurate mass (and thus, moles) of a solid substance
    is measured on a balance, dissolved in water, and then reacted with the substance
    being analyzed.
  2. As a standard solution—A measured number of moles of substance is present in
    a measured volume of solution, generally expressed as the molar concentration
    (or molarity) of the substance. A measured volume of the standard solution then
    reacts with the substance being analyzed.
    The reaction of the known substance with the substance to be analyzed, occurring
    in aqueous solution, is generally conducted by a titration procedure.
    The titration procedure requires a buret to dispense a liquid, called the titrant,
    into a ask containing the analyte (Figure 9.1a, page 128). For the acid–base titration
    studied in Part B of this experiment, the titrant is a standard solution of sodium
    hydroxide and the analyte is an acid.
    A reaction is complete when stoichiometric amounts of the reacting substances
    are combined. In a titration this is the stoichiometric point.1 In this experiment, the
    stoichiometric point for the acid–base titration is detected using a phenolphthalein
    indicator. Phenolphthalein is colorless in an acidic solution but pink in a basic solution. The point in the titration at which the phenolphthalein changes color is called the
    endpoint of the indicator (Figure 9.1b). Indicators are selected so that the stoichiometric point in the titration coincides (at approximately the same pH) with the endpoint of
    the indicator.
    Solid sodium hydroxide is very hygroscopic; therefore, its mass cannot be measured
    to prepare a solution with an accurately known molar concentration (a primary standard solution). To prepare a NaOH solution with a very well known molar concentration, it must be standardized with an acid that is a primary standard.
    In Part A of this experiment, dry potassium hydrogen phthalate, KHC8H4O4, is used
    as the primary acid standard for determining the molar concentration of a sodium
    hydroxide solution. Potassium hydrogen phthalate is a white, crystalline, acidic solid. It
    has the properties of a primary standard because of its high purity, relatively high molar
    mass, and because it is only very slightly hygroscopic. The moles of KHC8H4O4 used
    for the analysis is calculated from its measured mass and molar mass (204.44 g/mol):
    (9.1)
    From the balanced equation for the reaction, one mole of KHC8H4O4 reacts with one
    mole of NaOH according to the equation:

    The stoichiometric point is also called the equivalence point, indicating the point at which stoichiometrically equivalent quantities of the reacting substances are combined.
    In Part A.4 of the Experimental Procedure, an accurately measured mass of dry
    potassium hydrogen phthalate is dissolved in deionized water. A prepared NaOH solution in Parts A.1, 3 is then dispensed from a buret into the KHC8H4O4 solution until the
    stoichiometric point is reached, signaled by the colorless to pink change of the phenolphthalein indicator. At this point, the dispensed volume of NaOH is noted and recorded.
    The molar concentration of the NaOH solution is calculated by determining the
    number of moles of NaOH used in the reaction (equation 9.2) and the volume of NaOH
    dispensed from the buret.
    (9.3)
    Once the molar concentration of the sodium hydroxide is calculated, the solution
    is said to be “standardized,” and the sodium hydroxide solution is called a secondary
    standard solution.
    In Part B, an unknown molar concentration of an acid solution is determined. The standardized NaOH solution is used to titrate an accurately measured volume of the acid to
    the stoichiometric point. By knowing the volume and molar concentration of the
    NaOH, the number of moles of NaOH used for the analysis is
    (9.4)
    From the stoichiometry of the reaction, the moles of acid neutralized in the reaction
    can be calculated. If your acid of unknown concentration is a monoprotic acid, HA [as
    is HCl(aq)], then the mole ratio of acid to NaOH will be 1:1 (equation 9.5). However, if
    your acid is diprotic, H2A (as is H2SO4), then the mole ratio of acid to NaOH will be 1:2
    (equation 9.6). Your instructor will inform you of the acid type: HA or H2A.
    (9.5)
    (9.6)
    From the moles of the acid that react and its measured volume, the molar concentration of the acid is calculated:
    (9.7)
    Procedure Overview: A NaOH solution is prepared with an approximate concentration. A more accurate molar concentration of the NaOH solution (as the titrant) is
    determined using dry potassium hydrogen phthalate as a primary standard. The NaOH
    solution, now a secondary standard solution, is then used to determine the “unknown”
    molar concentration of an acid solution.
    Check with your laboratory instructor; stockroom personnel may have completed
    Parts A.1, A.2, and/or A.3 (or all of Part A). Begin the Experimental Procedure with
    the steps that follow those already completed by the stockroom personnel.
    You are to complete at least three good trials (1% reproducibility) in standardizing
    the NaOH solution. Prepare three clean 125-mL or 250-mL Erlenmeyer asks for the
    titration.
    You will need to use approximately one liter of boiled, deionized water for this
    experiment. Start preparing that rst.
  3. Prepare the stock NaOH solution. One week before the scheduled laboratory
    period, dissolve about 4 g of NaOH (pellets or flakes) (Caution: NaOH is very
    corrosive—do not allow skin contact. Wash hands thoroughly with water.) in
    5 mL of deionized water in a 150-mm rubber-stoppered test tube. Thoroughly

  4. Dry the primary standard acid. Dry 2–3 g of KHC8H4O4 at 110C for several
    hours in a constant-temperature drying oven. Cool the sample in a desiccator.
  5. Prepare the diluted NaOH solution. Decant about 4 mL of the NaOH solution prepared in Part A.1 into a 500-mL polyethylene bottle (Figure 9.2). (Caution: Concentrated NaOH solution is extremely corrosive and can cause severe skin removal!)
    Dilute to 500 mL with previously boiled,3 deionized water cooled to room temperature. Cap the polyethylene bottle to prevent the absorption of CO2. Swirl the solution
    and label the bottle.
    Calculate an approximate molar concentration of your diluted NaOH solution.
  6. Prepare the primary standard acid.
    a. Calculate the mass of KHC8H4O4 that will require about 15–20 mL of your
    diluted NaOH solution to reach the stoichiometric point. Show the calculations
    on the Report Sheet.
    b. Measure this mass (0.001 g) of KHC8H4O4 on a tared piece of weighing
    paper (Figure 9.3) and transfer it to a clean, labeled Erlenmeyer ask. Similarly, prepare all three samples while you are occupying the balance. Dissolve
    the KHC8H4O4 in about 50 mL of previously boiled, deionized water and add
    2 drops of phenolphthalein.

  7. Prepare a clean buret. Wash a 50-mL buret and funnel thoroughly with soap and
    water using a long buret brush. Flush the buret with tap water and rinse several
    times with deionized water. Rinse the buret with three 5-mL portions of the diluted
    NaOH solution, making certain that the solution wets the entire inner surface. Drain
    each rinse through the buret tip. Discard each rinse in the Waste Bases container.
    Have the instructor approve your buret and titration setup before continuing.
  8. Fill the buret. Using a clean funnel, ll the buret with the NaOH solution. 4 After
    10–15 seconds, read the volume by viewing the bottom of the meniscus with the
    aid of a black line drawn on a white card or see Figure 9.4 (the buret can be removed from the stand or moved up or down in the buret clamp to simplify this
    reading; you need not stand on a lab stool to read the meniscus). Record this initial
    volume according to the guideline in Technique 16A.2, using all certain digits
    (from the labeled calibration marks on the glassware) plus one uncertain digit (the
    last digit which is the best estimate between the calibration marks). Place a sheet
    of white paper beneath the Erlenmeyer ask.
  9. Titrate the primary standard acid. Slowly add the NaOH titrant to the first
    acid sample prepared in Part A.4. Swirl the flask (with the proper hand5
    ) after
    each addition. Initially, add the NaOH solution in 1- to 2-mL increments. As the
    stoichiometric point nears, the color fade of the indicator occurs more slowly.
    Occasionally rinse the wall of the flask with (previously boiled, deionized)
    water from your wash bottle. Continue addition of the NaOH titrant until the
    endpoint is reached. The endpoint in the titration should be within one-half drop
    of a slight pink color (see opening photo). The color should persist for 30 seconds. After 10–15 seconds, read (Figure 9.4) and record the final volume of
    NaOH in the buret.
  10. Repeat the analysis with the remaining standard acid samples. Re ll the buret
    and repeat the titration with the remaining two samples prepared in Part A.4.
  11. Do the calculations. Calculate the molar concentration of the diluted NaOH solution. The molar concentrations of the NaOH solution from the three analyses should
    be within 1%. Place a corresponding label on the 500-mL polyethylene bottle.
    Three samples of the acid having an unknown concentration are to be analyzed. Ask
    your instructor for the acid type of your unknown (i.e., HA or H2A). Prepare three
    clean 125- or 250-mL Erlenmeyer asks for this determination.
  12. Prepare the acid samples of unknown concentration. In an Erlenmeyer ask,
    pipet 25.00 mL of the acid solution. Add 2 drops of phenolphthalein.
  13. Fill the buret and titrate. Re ll the buret with the (now) standardized NaOH
    solution and, after 10–15 seconds, read and record the initial volume. Refer to
    Parts A.6 and A.7. Titrate the acid sample to the phenolphthalein endpoint. Read
    and record the nal volume of titrant.
  14. Repeat. Similarly titrate the remaining samples of the acid solution.
  15. Calculations. Calculate the average molar concentration of your acid unknown.
    Disposal: Dispose of the neutralized solutions in the Waste Acids container.
    Consult with your instructor.
    Save. Save your standardized NaOH solution in the tightly capped 500-mL
    polyethylene bottle for Experiments 10, 17, 18, and/or 19. Consult with
    your instructor.
    Disposal: Dispose of the neutralized solutions in the Erlenmeyer flasks in the
    Waste Acids container.

    Laboratory Questions
    Circle the questions that have been assigned.
  42. Part A.2. Pure potassium hydrogen phthalate is used for the standardization of the sodium hydroxide solution. Suppose
    that the potassium hydrogen phthalate is not completely dry. Will the reported molar concentration of the sodium
    hydroxide solution be too high, too low, or unaffected because of the moistness of the potassium hydrogen phthalate?
    Explain.
  43. Part A.3. The student forgot to prepare any boiled, deionized water for the preparation of the NaOH solution and then
    forgot to cap the bottle. Will the concentration of the NaOH solution be greater than, less than, or unaffected by this
    carelessness? Explain.
  44. Part A.7. A drop of the NaOH titrant adheres to the side of the buret (because of a dirty buret) between the initial and
    nal readings for the titration. As a result of the “clean glass” error, will the molar concentration of the NaOH solution
    be reported as too high or too low? Explain.
  45. Part A. The mass of KHC8H4O4 is measured to the nearest milligram; however, the volume of water in which it is dissolved is never of concern—water is even added to the wall of the Erlenmeyer ask during the titration. Explain why
    water added to the KHC8H4O4 has no effect on the data, whereas water added to the NaOH solution may drastically
    affect the data.
  46. Part B.2. The wall of the Erlenmeyer ask is occasionally rinsed with water from the wash bottle (see Part A.7) during
    the analysis of the acid solution. Will this technique result in the molar concentration of the acid solution being
    reported as too high, too low, or unaffected? Explain.

This page of the paper has 3093 words. Download the full form above. This paper looks to address the inquiries posed for the Moodle 2 task of the Team Management course. Present a conversation of what group is. What type(s) of group do you have in your association? A group in its least complex sort might be a bunch of people related along in work or movement. they’ll or probably won’t be sure by a standard target anyway individuals from a proficient group normally share a standard reason that ties them. The procedure normal for a group is that it’s one element in any event, assuming the individual colleagues that involve that group is additionally appallingly very surprising characters. In the present day and age, bunches are regularly various and in a few cases don’t appear to be even at a comparable area. the development in innovation has permitted such gatherings furthermore to viably associate with each other. notwithstanding the sort of group, a procedure normal for a group is that it relies upon joint effort between the colleagues so they’ll win an objective that one individual couldn’t have accomplished alone. There are a few factors that affect the adequacy of a group anyway 3 fundamental variables include: a convincing bearing, a hearty structure, and a helper setting (Haas and Mortensen, 2016). A convincing bearing alludes to a gathering of plainly laid out objectives that the group will progress in the direction of and is dazzled by. a strong structure alludes to a gathering of obviously sketched out jobs and duties regarding each colleague yet as appropriate individuals which will bolster the objectives of the group upheld their individual qualities. Another procedure normal for compelling gatherings is that it’s an equalization of aptitudes from all the individuals. Finally, an assistant setting alludes to an environmental factors that is contributory for prime execution. It might hold onto a few factors just as a prizes structure, preparing, foundation and so on the idea is to make an environmental factors any place each colleague will perform adequately to their best potential to accomplish the objectives of the group. As a gathering, we tend to concocted the end that we’ve frightfully various gatherings at our place of work. This assorted variety will be resolved inside the shift of ages, sex, race and nationalities. This adds to the group dynamic and acquires decent variety of thought and feeling to conversations that progressively makes for less difficult higher psychological procedure. Sometimes, it moreover brings about a qualification of suppositions and a couple of grating anyway by and immense the outcome is very positive. As aforesaid referenced, an ideal group is involved people with the best possible aptitudes to attempt to carry out the responsibility and furthermore the measures should be principally founded exclusively on those abilities as basic distinctive constraining variables. The gatherings might be named self-figuring out how to a larger than usual degree whereby a director exists and ought to dole out explicit undertakings anyway there’s still enough self-governance for singular colleagues or supporters of decide anyway those assignments are practiced. The self-guidelines with significance day by day activities, arranging give colleagues opportunity on anyway they have to achieve their designated assignments and deal with their own calendars with almost no to no inclusion from the board. the degree of inclusion of directors will change depending inside the organization and task. there’s no methodology that coordinates all outcomes anyway in our skill, over the top micromanagement brings about an annoyed and less cheerful men that is not as compelling. bunches should attempt to lease people with the best possible abilities and perspectives at that point trust them enough to permit them to attempt to carry out their responsibilities to a standard that is normal. What is implied by the “inward procedures” of a group? For what reason is it essential to oversee both the interior procedures and outside circumstances/requirements of a group? Interior procedures check with those endeavors and tips set up that began a structure inside which individuals from the group ought to work in order to achieve achievement. Viable inside procedures can guarantee safe quality, layout answerability and convey every course and target proportions of achievement. it’s fundamental to deal with each the inward procedures to ensure that the group keeps on being focused towards accomplishing the set-out objectives. the internal procedures can tell whether the individuals are having contradictions or not, such differences bring about clashes then this subverts the standard of work. it’s fundamental to deal with the internal procedures to remain all individuals from the group affected which they’re that spend significant time in their most crucial undertakings. Outside circumstances are those viewpoints that the colleagues can’t oversight even once exploitation the inward procedures of their group. A prove on account of improve your inner procedures is to acknowledge an item or administration that you just proposal from the demeanor of a customer. make by mental act that they’re remaining outside your association attempting in at the different advances expected to convey the product or administration to them. The point is to address these 3 inquiries: •​What jobs are worried in conveying your item or administration? •​What does one do at each progression? •​What changes on account of your activities? You should confirm what jobs are tangled in your business, here could be a rundown to use as a speedy: selling, Sales, Service conveyance, customer Support, investigation and Development, Sales Support, HR, Finance, Legal, Administration, IT, Purchasing, Business Strategy, General Management, and so forth. Each organization has its own way of life. sure every one of that gives an association’s capacity to challenge and recognize intensely to varieties inside the outer conditions – at long last, the association’s prosperity or disappointment – could be a kind of that have. The natural parts layout anyway the exchange proceeds, each as an independent structure substance and because of its outer climate. Dealing with each interior and outside imperative in equal are significant because of an indoor requirement is ordinarily among the administration of the business. partner outer imperative is outside the business and is hard to manage, if by any means. commonly inside and outer imperatives come and there’s a fine cross line between them. for instance, loan costs are an outer requirement, and this causes an indoor imperative in that it makes the fund money extra excessive for the business. Interior requirements – these are situation among the administration of the business that are constraining it accomplishing its yearning. The impacts of outside requirements are; dynamical shopper’s preferences people wish new item and administrations as by and by as they are accessible on to the market. They like to change to coordinate regardless of is trendy at that point. On the off chance that this occurs, at that point a business may see its business fall and it ought not be gainful or not endure. Contenders’ bring out new complete constantly to embrace to fight. They flood new promoting developments and progressions to change over someone clients. What are some viable procedures for improving effective group execution? In what capacity can these systems help to diminish dangers to group execution and inspiration? Group execution is really fundamental for prominent comes. one thing that pioneer is regularly considering is that the relations, associations and exhibitions of their group. Superior pointers show that prominent groups can all the time outmaneuver individuals working exclusively, especially inside the hot conditions or once fluctuated scopes of abilities and aptitudes are required. Having a zone with a group sets you up for extra recognized ampleness that you basically ne’er may reach while not any other individual.
