Chapter 11 Mixtures Mixtures

Classifying Substances All substances are classified into one of two groups: Pure substances Mixtures Pure substances are made of particles that are all exactly the same. Eg. Gold Pure substances can go through a physical change without the substance changing to a different substance. A Mixture is a physical combination of two or more substances.

Solutions A solution is a mixture of a solvent and a solute. A Solute dissolves in a solvent to form a solution Eg. Sugar A solvent is a substance in which a solute dissolves Eg. water
