There are two types of mixtures: Heterogeneous and Homogeneous. What is the difference between a heterogeneous mixture and a homogeneous mixture?

Homogeneous mixtures are solutions. The components that make them up are evenly distributed and the appearance of the solution is uniform throughout. Solutions can be solid, liquid, and gas. Brass is a metal alloy (solution) composed of the metals copper and zinc. Copper sulfate solution is an example of a liquid solution. Air is a solution of oxygen gas, carbon dioxide gas, nitrogen gas and others.

Heterogeneous mixtures are not solutions. The components of a heterogeneous mixture are visible and not uniform throughout. Some examples of heterogeneous mixtures are soil, granite, and conglomerate.

Heterogeneous mixtures have uneven distribution of components, visible phases, and varied properties in different parts. Homogeneous mixtures have uniform distribution of components, no visible phases, and consistent properties throughout.
