MixtureA mixture is made when two or more substances are combined.

GENERAL PROPERTIES OF A MIXTURE:The components of a mixture can be easily separatedThe components each keep their original propertiesThe proportion of the components is variable

TYPES OF MIXTURESHOMOGENEOUS: used to describe substances that look the same throughout. homogeneous substances have one phase and uniform composition.

HETEROGENEOUS: used to describe substances in which you can see more than one color or type of matter. heterogeneous substances have more than one phase and a nonuniform composition.

SolutionsIs where one of the substances dissolves in the other. The substance that dissolves is called the solute. The substance that does not dissolve is called the solvent.

Solutions are often classified as being eithersaturatedunsaturatedsupersaturated. it is important to note that all of these solutions will still be clear and homogeneous.SATURATED SOLUTIONShave the maximum amount of solute dissolved in them. no more solute can be made to dissolve.

UNSATURATED SOLUTIONShave less than the maximum amount of solute dissolved in them.

SUPERSATURATED SOLUTIONShave more than the maximum amount of solute dissolved in them. this is not normally possible.

Others MixturesSUSPENSIONS: are heterogeneous mixtures of a solid and a liquid in which the solid does not dissolve.

EMULSIONS: are a special type of suspension. this mixture consists of two liquids that do not mix. since the liquids do not mix, emulsions are heterogeneous.
