Based entirely on modern surface chemistry principles, which of the following intense physical or ch — Surface Chemistry Chemistry Question

💡 Solution & Explanation

A is strictly true: highly prolonged dialysis removes virtually all essential traces of the tiny amount of stabilizing electrolyte required for double-layer stability, causing precipitation. B is true: mutual coagulation inevitably occurs when oppositely charged sols rigidly neutralize each other. C is true: during prolonged electrophoresis, charged particles migrate entirely to the oppositely charged electrodes, heavily discharge, and immediately coagulate. D is generally false; adding an immiscible non-polar solvent may strictly cause a massive phase separation but not true coagulation of the aqueous dispersed phase.
