A reminder of the facts. A carboxylic acid is an organic acid that contains a carboxyl group (C(=O)OH) attached to an R-group. Yeast contains the enzyme zymase which acts as a catalyst for the reaction; Wine contains ethanol of a concentration up to about 14 -15%. The concentration of the solution greatly affects the dissociation to form the hydrogen ion and the conjugate base, acetate (CH 3 COO ).At a concentration comparable to that in vinegar (1.0 M), the pH is around 2.4 and only around 0.4 percent of the acetic acid molecules are In this reaction the ethanol is oxidised to ethanal by removing two hydrogen atoms. This makes acetic acid a monoprotic acid with a pKa value of 4.76 in aqueous solution. Mechanism of acidic hydrolysis Ethanol also undergoes bacterial oxidation to ethanoic acid. Fermentation is a slow reaction. This is an example of an esterification reaction where one molecule acetic acid (also called ethanoic acid) reacts with one molecule ethanol, yielding one molecule ethyl acetate (a bimolecular second-order reaction of the type A + B C): .
