Question

Which is the correct order of stability of solution  A) True < Colloid < Suspension B) Colloid < Suspension < True C) Colloid < True < Suspension D) Suspension < Colloid < True​

Answer 1

D

Suspension < Colloidal < True solution

Answer 2

Correct stability order of solution is - Suspension < Coloid < True. (OPTION D)

STABILITY OF SOLUTIONS -

• The Stability of the solution depends upon the particle size of the dispersed phase and the medium.
• The Particle size of the true solution is very small up to 1 nanometre.
• The particles do not settle down upon standing in true solution.
• The size of a particle of the colloidal solution is small in comparison to the size of suspension particles.
• In suspension, particles settle down at the bottom due to their large size ranging from 1 - 50 micrometers.
