Detailed explanation-1: -The stability of lyophilic as well as lyophobic colloids is due to presence of charge on the particles.

Detailed explanation-2: -DLVO theory is a theory of colloidal dispersion stability in which zeta potential is used to explain that as two particles approach one another their ionic atmospheres begin to overlap and a repulsion force is developed.

Detailed explanation-3: -The classical Derjaguin, Landau, Verwey and Overbeek (DLVO) theory describes the outcome of electrostatic repulsion energies versus London–van der Waals attraction energies, as a function of interparticle distance, acting upon charged particles suspended in a liquid.
