Is a true solution different from a colloid solution?

The main difference between a true solution and a colloidal solution is that a true solution is a homogeneous single-phase system whereas a colloidal solution is a heterogeneous two-phase system. A true solution is a homogeneous mixture and a colloidal solution is a heterogeneous mixture.

What are the components of colloidal solution?

Components of the Colloidal Solution: There are two components of the dispersed phase of the colloidal solution and the dispersion medium. The solvent-like component of the colloidal solution is called the dispersed phase and the solvent-like component is called the dispersion medium. The dispersed phase and the dispersing medium may be solid, liquid or gaseous.
