We can improve the results by;
1. Reducing the human error, most of the eroor in the result comes because of human errors.
2. Errors in the apparatus, some apparatus doesn't have the standard volume which is written on it.
3. By proper handling of chemicals during the experiment, it will reduce error in the results significantly.
- Percent errors shows how large the error is, the less the perfect error the more accurate the result is.

no calculations needed just discussion How well did titration work to find the percent by mass of acetic acid in vinegar? What could you do to improve your results? Is there anything that you can think of that would improve the experiment? Discuss the percent error.
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.
(TITRATION) What would be the calculations based on the trial data gathered? I obtained 50mL of NaOH solution and then pipetted 5.0mL of pickle juice into an Erlenmeyer flask. I then added 50mL of distilled water and 2 drops of indicator. Molarity of NaOH: 0.1001M Trial 1 Vinitial: 24.50 mL Vfinal: 45.72 mL Trial 2 Vinitial: 2.42 mL Vfinal: 23.74 mL Trial 3 Vinitial: 23.74 mL Vfinal: 44.22 mL Calculations Assume that the acid present in your food sample is...
I am supposed to find the individual and average weight percents of acetic acid in vinegar and the relative percent error between my average results and the manufacturers listed value. Data 6ml vinegar @ 5% acetic acid 3.585g vinegar 42.2ml of NaOH @ 0.100M I'm not sure how to do this at all and want to understand. I know we need to use the molarity equation somewhere. If anyone can list the steps I need to take to answer the...
