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

Options

  1. AFilm of lyophilic sol is formed over lyophobic sol
  2. BLyophilic sol is dispersed in lyophobic sol
  3. CFilm of lyophobic sol is formed over lyophilic sol
  4. DLyophobic 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.
