Question

The process of dispersing a freshly prepared precipitate into colloidal form is called ______.

Answer 1

The process of dispersing a freshly prepared precipitate into colloidal form is called peptization.

Explanation:

Peptization involves adding a suitable electrolyte (called a peptizing agent) to a freshly formed precipitate, which causes the precipitate particles to disperse and form a colloidal solution. This happens due to the adsorption of ions on the precipitate particles, creating electrostatic repulsion that stabilizes the colloidal particles in the medium.
