Question

Peptization is a process of ______.

विकल्प

• precipitating colloidal particles

• purifying colloidal particles

• dispersing the precipitate into colloidal state

• none of the above

Answer 1

Peptization is a process of dispersing the precipitate into colloidal state.

Explanation:

Peptization is the process of converting a freshly prepared precipitate into a colloidal solution by adding a suitable electrolyte called a peptizing agent, which causes the precipitate particles to disperse due to electrostatic repulsion. For example, ferric chloride added to ferric hydroxide precipitate forms a colloidal solution.
