Mike Grambow Antacid Analysis This experiment uses an acid-base titration as a method to determine the percent acetic acid in vinegar and to determine the neutralization capacity of antacid tablets, specifically tums. In part two, vinegar was titrated with 0.3M NaOH until the solution turned a faint pink color. 31.3 ml of NaOH were needed to titrate the solution. Hence, the molarity of acetic acid in the vinegar was .4695M, and it turned out that the vinegar was 2.7% acetic acid, which is a relatively low amount. It was observed that the more NaOH that was added to the solution the darker pink the solution got because of the indicator phenolphthalein. Part three was to find the percent composition of the active ingredient, CaCO 3 , in an antacid. Thymol blue was used as a pH indicator in HCL. Since HCL is a strong acid, the solution was originally red, or more of a pink color. After a tums was placed in the solution, it was titrated with the base NaOH. As the pH started to balance in the solution it started to turn a shade of peach then completely yellow.
