(C) Colloids : A colloid is a kind of solution in which the size of solute particles is intermediate between those in true solutions and those in suspensions. The size of solute particles in a colloids is bigger than that of a true solution but smaller than those of a suspension. Dispersed particles The solute particles are also called ‘dispersed particles’. Dispersion medium Solvents are also known as dispersion medium. Solution, suspensions and colloids differ in the size of solute particles, the size of particles being minimum in solutions and maximum in suspensions.
