Question

Can we regard heterogeneous mixtures as solutions?

Answer 1

Almost all the substances are made up of very small particles called molecules. ... Not all solid substances dissolve well in water. Chalk remains suspended in water as small particles. A suspension is a heterogeneous mixture, it is always cloudy: you cannot or can hardly see through it.

Answer 2

Chalk remains suspended in water as small particles. A suspension is a heterogeneous mixture, it is always cloudy: you cannot or can hardly see through it. Mixtures of solid substances never give a homogeneous mixture. A solution is a homogeneous mixture of a substance (a solute) and a solvent, usually water.
