Paragraph: The most important property of hydrophobic colloidal dispersions is that the particles carry electric charge. This charge is largely responsible for the stability of lyophobic sols Paragraph: Which of the given statement(s) is/are correct?

Options

  1. AThe particles of a colloid carry similar charges
  2. BThe repulsive forces between charged particles provide stability to the colloidal solution
  3. CThe particles of a colloid carry equal and opposite charges
  4. DThe attractive forces between these charged particles provide stability to the sol by lowering potential energ

Correct answer

B. The repulsive forces between charged particles provide stability to the colloidal solution

Step-by-step solution

The particles of sol carry equal and similar charge which causes repulsion among particles thus preventing coagulation
