1.1 Abstract / Summary
Vinegar is a liquid consisting mainly of acetic acid ( and water or basically it is a dilute solution of acetic acid. This experiment is to determine the molarity of a solution and the percent by mass of acetic acid in vinegar by titration with a standardized sodium hydroxide solution. The experiment is divided into two parts where the first one is to prepare standardizing sodium hydroxide solution which will be titrated to potassium hydrogen phthalate, solution and the second one is determining the molarity and percentage by mass of the acetic acid in vinegar. 6 g of NaOH solid is used to dilute with distilled water to prepare a 250 mL of 0.6M sodium hydroxide. pH electrode will be immersed into the solution and a grph of pH versus NaOH is obtained. The next part is to determine the molarity of acetic acid and mass percent in vinegar where the vinegar is diluted as the same way in previous part. The titration is repeated twice for both parts to get accurate readings. Average molarity of acetic acid is 1.0147 M. Average percent by mass of acetic acid in vinegar is 6.15 %.
