Solution
- Most of chemical people use at home or on the job are solutions. Most of chemical you use in your chemistry lab are in solution because reactions foten occur faster in solution. The solutions are stable and homogeneous mixtures.

Suspension
- It is a mixture that appears uniform while being stirred, but separates into different phases when agitation ceases. For example there is oil and water mixture. Oil and water never dissolve nor mix together. They will have two lay so that we can see oil in the top and water in the bottom.

Colloids
- It is a mixture that is not completely dissolved so that you can see more than one substance. For example, there are sugar and water or salt and water mixtures. It is dissolved but not completely so that you can see a little particle floating in water.

Describing Solutions
- The simplest solutions have two ingredients. The solvent and the solute. The solvent is usually present in a larger amount than the solute, and chemists think of the solute as dissolving in the solvent.
