WHAT IS A MIXTURE?

A mixture is a substance made up of two or more types of matter that aren't chemically combined.
There are two types of mixtures:
Homogeneous mixtures: It is a mixture that has a consistent color and texture. Every part of an homogeneous mixture has the same properties.

A solution is a mixture of one or more liquids, with one or more other substances. In a solution, the substances are dissolved in the liquid.
The liquid components of a solution are called solvents. The other components are called solutes.
