Chapter 1
Mixtures
BIG IDEAS
• Mixtures are materials made up of two or more substances. Each substance in a mixture retains its own characteristic properties.
• Solutions, suspensions, and colloids are mixtures that have specific uses for humans.
• The components of a mixture can be separated using different techniques such as decantation, evaporation, filtration, sieving, and using a magnet.

CHAPTER OVERVIEW
Matter, in different states, may be physically combined to form a new substance. When materials are put together, they may form a heterogeneous mixture, which has parts that are distinguishable from one another, or a homogeneous mixture, which has parts that are alike. Mixtures can be in the form of solutions, suspensions, or colloids, which are commonly used at home and for many different applications.
The components making up a mixture can be separated by simple mechanical techniques such as decantation, evaporation, filtration, sieving, and using a magnet to produce pure substances.
