Discussion Experiment 7: Antacid Analysis and the Determination of the Percent Acetic Acid in Vinegar was about using acid-base titration as a method to determine the percent acetic acid in vinegar and to determine the neutralization capacity of antacid tablets, as well as to lear the technique of standardizing a solution. To determine the Molarity of NaOH, three solutions of KHP were created, the masses of the KHP mixed with each solution were 1.20g, 1.31g, and 1.28g, respectively. 250.0 mL of 0.3 M NaOH solution was then placed into a 500 mL flask, and stoppered, so that the CO2(g) in the air would not react with the NaOH solution, then after was poured into a burette. From there, the initial volume of the burette was recorded and then NaOH from the burette would then be dripped into the KHP solution and stirred until the KHP solution was titrated with the NaOH solution (when the solution turned pink, because 0.1% of phenolphthalein was added to the KHP solutions). The final volume in the burette was then recorded and the Molarity of the NaOH
