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.
Note that, acid chlorides are also named as acyl chlorides or carboxylic acid chlorides.
Aqueous acid chloride is a very acidic solution due to formation of a strong acid and a weak acid. This hydrolysis reaction is a elimination reaction and water is participated as a reagent. This reaction completely converts acid chloride to carboxylic acid and HCl.
Some examples of hydrolysis of acyl chlorides are explained below.
Ethanoic acid and HCl are given as products by the hydrolysis of ethanoyl chloride. Ethanoyl chloride is soluble in water and form a strong acidic solution due to HCl acid.
Benzoyl chloride hydrolysis give benzoic acid and HCl as products. Benzoic acid is a white precipitate which is a not soluble organic compound in water.
