hydrolysis of esters

If you do this, the mixture is flooded with hydrogen ions. These are picked up by the ethanoate ions (or propanoate ions or whatever) present in the salts to make ethanoic acid (or propanoic acid, etc). Because these are weak acids, once they coine with the hydrogen ions, they tend to stay coined. The carboxylic acid can now be distilled off.
