Question

Distinguish between true solution and colloidal dispersion.

Answer 1

A solution is a mixture of two or more substances in the liquid phase. A dispersion is a system composed of a mixture of two or more substances that exist as a two-phased system. Some solutions are transparent while other solutions are opaque. A true solution is a clear transparent solution whereas a colloidal dispersion is a turbid translucent mixture. The main difference between true solution and colloidal dispersion is that a true solution is essentially in the liquid phase whereas a colloidal dispersion can exist in different phases.
