A homogeneous mixture of two or more substances is called a true solution. It consists of solute and solvent. The particle size of a true solution is less than 1 nanometer. A suspension is a heterogeneous mixture in which the solute particles do not dissolve but remain suspended throughout the bulk of the medium. A colloid is a mixture that is actually heterogeneous but appears to be homogeneous as the particles are uniformly spread throughout the solution. (i) 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
