What is Acetic Acid Concentration in Vinegar about?

This document describes a procedure to determine the concentration of acetic acid in two brands of vinegar through titration. 25mL of each vinegar sample was diluted and titrated with 0.1M sodium hydroxide solution until the phenolphthalein endpoint was reached. The average titrant volume was used to calculate the moles of acetic acid present, from which the molarity of acetic acid in the original and diluted vinegar samples was determined. The concentration of acetic acid in one brand was found to be 0.084
