Vinegar Analysis

Experiment: Analysis of Vinegar

Introduction

This is another quantitative analysis experiment. Look at the label of many items. It tells you how much of key substances is there. Vinegar should have the right amount of acetic acid in it for pickling and other household tasks. Tell students-READ THE LABEL. As experienced science students, they can know perform an analysis to determine the acetic acid content of household vinegar. This is representative of how all commercial materials end up with reported contents or analysis on label.

General Information

The basic principle behind titration is that one solution is added to another to result in a chemical reaction.

The process is set so exactly enough of one material is added to completely react with the other according to the equation for the reaction.

Here is an example. I use Ag+ + Cl- ч AgCl as an example of determining amount of chloride ion in, say, sea water. We want to determine the % Cl- in sea water. Remember
