For vinegar titration in this experiment, would the
following errors cause the % acetic acid in vinegar determined to
be (A) too large, (B) too small, (C) no effect, or (D) not enough
information to answer. Assume that the mistake given is the only
mistake made in the experiment. EXPLAIN.
1.) The burst is rinsed with distilled water, but not NaOH solution
before the vinegar sample is titrated.
2.) After standardization, the NaOH solution is not stoppered and
obsorbs CO2 (from the air) before titration is carried out.
3.) The vinegar sample absorbs CO2 from the air before titration is
carried out.
4.) The endpoint is too pink during standardization of
the NaOH solution.
5.) The endpoint is too pink during the titration of the vinegar
solution.
6.) The flask is not dry when the vinegar solution is added into
it.

chem 110 experiment 12 tritation vinegar need help fast please!!! The density of vinegar is 1.01 g/mL. How would this information affect your experimental results. 2. Weak acids, such as acetic acid, typically have an odor, whereas strong acids often do not. Explain this is so EXPERIMENT # 1 2 ACETIC ACID CONTENT OF VINEGAR Objectives Use chemical pll indicators to find endpoints of acid base titrations Use the burets to undertake chemical titrations PreLab questions i.

A vinegar (acetic acid) solution of unknown concentration was titrated to the light pink endpoint with the standardized NaOH solution. The weight volume % of the vinegar solution were calculated. Molecular formula of Acetic acid: C2H4O2 Volume of vinegar sample titrated (ml) 5.00 Volume of NaOH required to neutralize vinegar in (mL) 8.74 Concentration of NaOH in mol/L, 0.1979 Calculate the weight/volume percentage of the vinegar solution (g/100 ml).
During the calculations for titration of vinegar experiment, you determined the molar mass of KHP by using the mass of K, H, and P instead of using KHC8H4O4. How would this change your results? Explain. We had to find the mass of KHP, moles of KHP, moles of NaOh, and moles of acetic acid, molarity of vinegar titrated, mass of acetic acid titrated in grams, and w/v % of acetic acid in vinegar
• Material from the Acid-Base Titration Experiment. If you were to overtitrate without realizing it, would the following results come out too high, too low or unchanged? Be able to explain your answer. concentration of acetic acid in vinegar • mass percent of acetic acid in vinegar? o What is the purpose of adding deionized water to the vinegar in the Erlenmeyer flask? Does it affect the endpoint? Explain why or why not.
Prelab Activity: Titrations Continued – Titration of Household Products A 2.40 g sample of vinegar was added to an Erlenmeyer flask along with 100 mL of deionized water and 3 drops of phenolphthalein indicator. It took 22.15 mL of 0.0981 M NaOH (aq) to reach the faint pink endpoint. The following balanced chemical equation represents the chemistry of the titration: NaOH (aq) + CH3COOH (aq) à CH3COO–Na+ (aq) + H2O (l) Calculate the mass % of acetic acid (CH3COOH) in...
I need it right now, please help me?? PROCEDURE PART I: DILUTING THE VINEGAR SOLUTION The vinegar solution must be diluted by a factor of 5 to be suitable for titration. 1. Obtain - 20 ml of the stock vinegar solution from the fume hood. 2. Using the 10-ml. pipet, pipet" 10 mL of the stock solution to a 50-ml volumetric flask. 3. Fill the volumetric flask to the calibration line with distilled water. Be sure not to go over...
acetic acid is an important ingredient of vinegar. a sample of 50.0 ml of a commercial vinegar is titrated against a 1.00 M NaOH solution. What is the molarity of acetic acid present in the vinegar if 5.75 ml of the base are needed for the titration?
