Hydrolysis Definition

By

Definition: Hydrolysis is a type of decomposition reaction where one reactant is water.

The general formula of a hydrolysis reaction is:

AB + H2O → AH + BOH

Organic hydrolysis reactions involve the reaction of water and a ester. This reaction follows the general formula:

RCO-OR' + H20 → RCO-OH + R'-OH

the dash denotes the covalent bond that is broken during the reaction.
Examples:
Dissolving a salt of a weak acid or base in water is an example of a hydrolysis reaction.
