Question

The correct statement(s) related to colloids is (are):

Options

• The process of precipitating colloidal sol by an electrolyte is called peptization.

• Colloidal solution freezes at high temperature than the true solution at the same concentration.

• Surfactants form micelle; critical micelle concentration (CMC) depends on temperature.

• Micelles are macromolecular colloids.

Answer 1

Colloidal solution freezes at high temperature than the true solution at the same concentration.

Surfactants form micelle; critical micelle concentration (CMC) depends on temperature.

Explanation:

• Peptization is the process of converting precipitate into colloidal sol, not precipitating colloidal sol by an electrolyte.
• Micelles are associated colloids formed by surfactants, not macromolecular colloids.
