The nature of electric charge on colloidal particles can be experimentally determined by — Surface Chemistry Chemistry Question

💡 Solution & Explanation

The charge on colloidal particles is directly demonstrated and determined by electrophoresis, where particles move to the oppositely charged electrode. Electro-osmosis involves the movement of the oppositely charged dispersion medium, which indirectly identifies the charge of the held colloidal particles. Therefore, correct answer is B,C.
