Homework Help: Experiment about efficiency of bisulphite as wine preservative

  1. Sep 30, 2008 #1
    1. The problem statement, all variables and given/known data
    Could you suggest an experiment to determine the efficiency of sodium hydrogensulphate(IV) as a wine preservative?

    2. The attempt at a solution
    I just think that since wine contains ethanol, which would be oxidized in air to form ethanoic acid slowly, by comparing the pH value of the wine between a sample exposed to air and a control can the efficiency be determined.

    But how can I CALCULATE the efficiency? or are there other better and more convenient ways?
