1. Mixtures and Solutions Notes  Pure substance: matter that has definite chemical and physical properties  Mixture: matter that contains two or more substances that differ in physical and chemical properties  Soluble: when a solute dissolves in a solvent  Insoluble: when a solute does not dissolve in a solvent  Solvent: the substance in a solution that dissolves the solute  Pure substance: matter that has definite chemical and physical properties  Mixture: matter that contains two or more substances that differ in physical and chemical properties  Soluble: when a solute dissolves in a solvent  Insoluble: when a solute does not dissolve in a solvent  Solvent: the substance in a solution that dissolves the solute

2.  Solute: the substance that dissolves in a solvent. Solutes may be solids, liquids, or gases  Solution: a homogeneous mixture of a solvent and solute  Dissolve: When a solvent is mixed with a solute to make a solution  solubility: the amount of solute that will dissolve in a solvent at a given temperature  saturated solution: a solution that will not dissolve any more solute at a given temperature.  evaporation: to change from a liquid to a gas at or below the boiling point, one method of separating dissolved substances from a solution  Solute: the substance that dissolves in a solvent.

3.  filtration: the process of separating a solid and a liquid by passing a mixture of the two through filter paper. The liquid will pass through the paper and the solid will stay in the paper.  residue: the solid that stays in the filter paper when a mixture is filtered  filtrate: the liquid that goes through the filter paper when a mixture is filtered  sedimentation: the process by which a solid settles out from a solid/liquid mixture.  sediment: the solid that collects below the liquid  Whether a solvent will dissolve a solute rule of thumb: likes dissolve likes!!  Chromatography: a process used to separate different solutes from a solution by passing them through a medium.  chromatogram: the patterns produced on the paper  filtration: the process of separating a solid and a liquid by passing a mixture of the two through filter paper.
