What is a colloidal solution ? How is it different from a true solution with respect to dispersed particle size and homogeneity ?

Explanation

A heterogeneous system in which one substance is dispersed as large particles in another substance is called colloidal solution.
`to` In colloidal solution the particle size of the dispersed phase is ot the order of I `m mu` -`1 mu` where as in true solution the particle size of the solute are the order of `m mu` or less.
`to`Colloidal solution is a heterogeneous binary system where as true solution is a homogeneous binary system.
