TYPES OF MIXTURES
There are two main types of mixtures:
1. homogeneous
2. heterogeneous
Homogeneous Mixture
A homogeneous mixture is a combination of two or more substances which has a uniformed composition throughout. This means that the components of the mixture are uniformly distributed. for example, salt in water
Heterogeneous Mixture
A heterogeneous mixture is one that has a non-uniformed composition throughout. For example, chalk dust in water.
There are mixtures which fall into these categories. There are three main kinds:
1. solutions
2. suspensions
3. colloids
Solutions
Solutions are homogeneous mixtures consisting of a solvent (the substance that does the dissolving) and a solute (the substance being dissolved). They are in one uniformed state. Solutions tend to take the state of the solvent.

Suspensions
Suspensions are heterogeneous mixtures consisting of particles held floating (suspended) in a liquid. If left undisturbed, the particles eventually settle out. The particles of a suspension are larger than those of a solution.

Colloids
A colloid is a mixture in which the solute is broken down into pieces that are too small to see with the naked eye, but are large enough to interfere with visible light. As a result, colloids are cloudy. Some examples of colloids are: aerosol sprays, insecticides, smog, fog, clouds, mayonnaise,
