When a positively charged sol is mixed with a negatively charged sol in suitable proportions, the result is:

  1. Apeptization of both sols
  2. Bmutual coagulation of both sols
  3. Cno change, because the sols are of different substances
  4. Da more stable mixed sol

Answer: B

Oppositely charged sols neutralise each other's charge when mixed in the proper ratio. The particles then aggregate and precipitate, which is called mutual coagulation.
