Peptization is the method of producing stable colloids using an electrolyte to split up and distribute a precipitate into the colloids. Peptization utilizes the charges to produce colloids from the precipitate. The electrolyte used in the process is called a peptizing agent.

What is peptization and explain its cause?

Peptization is a process of passing of a precipitate into colloidal particles on adding suitable electrolyte. The electrolyte added is known as peptizing agent. ... On adding insufficient quantity of very dilute HCl solution to the freshly precipitated aluminium hydroxide, a sol of aluminium hydroxide is obtained.

What is peptization explain its mechanism?

When electrolyte is added to the freshly precipitated substance the particles of the precipitate preferentially absorb one particular type of ions of the electrolyte and get dispersed due to electrostatic repulsions giving particles of colloidal size and hence cause peptization.
