Esters are chemical compounds that are derived from organic or inorganic acids were at least one hydroxyl group is replaced by an alkoxy group. Hydrolysis is a simple reaction with water. It can be a reverse of water condensation where it involves the ejection of a water molecule when two molecules form together to form a larger molecule.
Hydrolysis of ester by dilute acid and water
In the above reaction dilute acid is used as acid catalyst.
