What happens when a lyophilic sol is added to a lyophobic sol?

What happens when a lyophilic sol is added to a lyophobic sol?

Options

  1. A

    Film of lyophilic sol is formed over lyophobic sol

  2. B

    Lyophilic sol is dispersed in lyophobic sol

  3. C

    Film of lyophobic sol is formed over lyophilic sol

  4. D

    Lyophobic sol is coagulated

Correct answer

A.

Film of lyophilic sol is formed over lyophobic sol

Step-by-step solution

Film of lyophilic sol is formed over lyophobic sol as lyophilic sol acts as a protective colloid. Lyophobic solutions are unstable in nature. When a lyophilic sol is added to lyophobic sol, stability of lyophobic sol increases due to a protective film of lyophilic sol present over the lyophobic sol.
