All colloidal dispersions have

Options

  1. Alow osmotic pressure
  2. Bno osmotic pressure
  3. Chigh osmotic pressure
  4. Dvery high osmotic pressure

Correct answer

A. low osmotic pressure

Step-by-step solution

Colloidal particles are bigger aggregates. Thus, the number of particles in the colloidal solution is comparatively small as compared to true solution. Hence, the values of colligative properties (e.g., osmotic pressure) are of small order as compared to values shown by true solutions at the same concentrations.
