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 statements is/are correct?

Options

  1. AAn acidic dyestuff hydrolyses yielding hydroxyl ions in solution and acquires an equivalent amount of positive
  2. BAn acidic dyestuff ionises furnishing H ⁺ ions in solution and thereby leaving an equivalent amount of negativ
  3. CA basic dyestuff hydrolyses yielding H ⁺ ions in solution and thereby leaving the particles with an equivalent
  4. DA basic dyestuff ionises yielding hydroxyl ions in solution and thereby leaving an equivalent amount of positi

Correct answer

D. A basic dyestuff ionises yielding hydroxyl ions in solution and thereby leaving an equivalent amount of positi

Step-by-step solution

Acidic dyestuff furnish H ⁺ Negative Colloid Basic dyestuff furnish OH ⁻ Positive Colloid
