MIXTURES

Mixtures are made of two or more substances that are mixed together but can be separated from each other. Mixtures can be made from various combinations of solids, liquids, or gases. The substances in a mixture do not permanently change in the mixture. The substances keep their separate properties. Some examples of mixtures are cereal and milk, trail mix, or salad.

SOLUTIONS

One type of mixture is a solution. Solutions are mixtures that are composed of substances that mix so completely (by dissolving) that they cannot be distinguished as separate substances. The greatest amount of substance in a solution is called the solvent. It is usually the liquid. Water is a good solvent. It is sometimes called the “universal solvent” because so many things will dissolve in it. The least amount of substance in a solution is the solute. It is usually the solid (sugar).
