Formula / equation AB + H₂O → AOH + BH
Unit Dimensionless

In depth

Hydrolysis is the reverse of condensation and is usually accelerated by acid or base catalysis, or by enzymes in living systems. Salts of weak acids or bases hydrolyse in water to give non-neutral solutions, and hydrolysis is the digestive process that breaks food polymers into absorbable units.

Examples in the real world

Sucrose hydrolysing to glucose and fructose; an ester refluxed with dilute acid giving back its acid and alcohol.
