The stabilization of a dispersed phase in a lyophobic colloid is due to

View answer and explanation

Correct option: C

The formation of an electrical layer between two phases

Option C (The formation of an electrical layer between two phases) is correct because the stabilization of lyophobic colloids is due to the electrical double layer formed at the interface.
