WebTable 1: A comparison of the size of particles in true solutions, colloidal solutions and suspensions: Colloidal system exhibiting properties of a fluid is known as sol. Sols arc sometimes almost as thick as jelly, when they are called gels. Sols are subdivided into: (a) Lyophobic (solvent hating) and (b) Lyophilic (solvent loving) colloids. WebLyophobic colloids are liquid hating colloids (Lyo means solvent and phobic means hating). When these colloids are mixed with the suitable liquid, very weak force of attraction exists between colloidal particles and liquid and system does not pass into colloidal state readily . Hence correct answer is option 'A'.
