Colloid
A mixture in which very small particles of one substance are distributed evenly throughout another substance.
Suspension
a type of heterogeneous mixture where solid particles do not dissolve in a liquid solution.

light scattering in colloidal dispersion, while showing no light in a true solution. This effect is used to determine whether a mixture is a true solution or a colloid. -JOHN TYNDALL
Solute
a substance that is dissolved in a solution
Saturation
the condition in which one substance takes up as much space as possible within another substance and it can take no more molecules. Other words for saturation include equilibrium.
Concentration
the measurement of the number of particles present in a given volume, often in a mixture or solution.
Dilution
the process of decreasing the concentration of a solute in a solution
