Question

How electrophoresis lead to coagulation of gold sol.?

Answer 1

The phenomenon of movement colloidal particles under the influence of applied electric field is called electrophoresis. ... For example, if BaCl2 solution is added to As2S3 sol, the Ba2+ ions are attracted by the negatively charged sol particles and their charge gets neutralised. This leads to coagulation.
