The colloidal particles are neutralized by the oppositely charged electrolyte ions. The destabilization of an lyophobic colloid occurs at the electrolyte concentrations exceeding the value of the critical coagulation concentration.
WebElectrostatic repulsion is the result of interaction between the electrical double layers surrounding particles or droplet. When charged colloidal particles in a dispersion approach each other such that the double layers begin to overlap (particle separation becomes less than twice the double-layer extension), repulsion occurs.
