Statement A is also generally not strictly true in the sense of uniform distribution like a true solution, but B is the most definitive and fundamental falsehood about the nature of colloids.<\/section>\n","protected":false},"excerpt":{"rendered":"<p>Which among the following is NOT true with respect to colloidal solution ?
