Answer 2

It is heterogeneous, is not true about colloidal system.

Explanation:

A colloid is defined as a solution in which solute particles are microscopically dispersed into the solvent and these particles remain suspended into the solution.

A collide is a mixture in which particles are suspended into the solution. For example, milk is a colloidal solution.

Particles of a colloid do not settle down under gravity and they are visible under a microscope. A colloidal solution can also considered as a homogeneous solution but some of them can be heterogeneous solution.
