How does boiling contribute to coagulation?

Options

  1. ABoiling increases the charge on particles, preventing coagulation.
  2. BBoiling disrupts the adsorbed layer, reducing particle charge and leading to coagulation.
  3. CBoiling enhances the stability of colloidal particles.
  4. DBoiling has no effect on colloidal particles.

Correct answer

B. Boiling disrupts the adsorbed layer, reducing particle charge and leading to coagulation.

Step-by-step solution

According to the paragraph, when a sol is boiled, the adsorbed layer is disturbed due to increased collisions with the molecules of the dispersion medium. This reduces the charge on the particles and ultimately leads to settling down in the form of a precipitate.
