Carboxylic acid chloride such as ethanoyl chloride, benzoyl chloride hydrolysis easily in the water and give carboxylic acid and HCl as the products. We know carboxylic acid is a weak acid and HCl is a strong acid in the water.
Aqueous carboxylic acid chloride is a very acidic solution due to form of strong acid and weak acid. This hydrolysis reaction is a elimination reaction and water is participated as a reagent. This reaction completely converts carboxylic acid chloride to carboxylic acid and HCl.
Some examples are explained below.
Ethanoic acid and HCl are given by the hydrolysis of ethanoyl chloride.
Benzoyl chloride hydrolysis and give benzoic acid and HCl. Benzoic acid is a white precipitate.
