explain the effect of each of thes following sources of error on the molarity of acetic acid as determined in this experiment stating whether the concentration of acetic acid obtained would be too high or too low.
a. The buret is contaminated with an acid solution
b. The buret contains a larger air bubble in the tip, which disappears in the course of a titration.
c. A small volume of the acid solution is spilled when you transfer it into the erlenmeyer flask.
Homework Answers
In the titration relation M1V1 = M2V2 means that the product of molarity and volume will remain constand for monoprotic acid and base.

1. Assume that your vinegar contained a small amount of citric acid (a triprotic acid). Using the same experimental data, would vou expect the molarity of this sample to be POST-LAB QUESTIONS the same as or different than a sample which contained only pure acetic acid? 2 Assume that the tip of your buret was not properly filled with NaOH solution. It contained an air bubble which was eliminated during the titration. Would the caleulated molarity of the vinegar be...
