Chemistry Course Work - Neutralisation of ethonoic acid

Who’s cheating on the vinegar?

Task:

A chip shop owner buys his vinegar from 4 different suppliers A, B, C and Safe way. He suspects that at least one of them waters down the vinegar supplied to them by the manufacturer.

You are the analytical chemist assigned to investigate this. You have already planned an experiment that will give you the evidence you need.

The following results have been taken from a similar experiment. Your task is to analyse these results and present your conclusion. You must then evaluate the experiment by assessing its success in answering the original question, explaining any anomalous results, and suggesting any possible improvements.
