A solution is a homogeneous mixture of molecules, ions, or atoms of two or more different substances. It consists of a solute and a solvent. Solutions may exist in any of the three states of matter - solid, liquid and gas. Thus, there are three general types:
Liquid Solution
• Solid Solution
Gaseous Solution
These may be sub-classified based on the final state of the solution (state of solvent) and the normal state of the pure solute.
Examples of solutions are the following:
1. Sugar in water (Liquid Solution because the solvent is liquid and solute is solid)
2. Oil in gasoline (Liquid Solution) 3. Gold in Copper (Solid Solution)
4. Naphthalene in air (Gaseous Solution)
5. Oxygen in Air (Gaseous Solution)
A Colloidal Dispersion or Colloids are heterogeneous mixtures in which the size of
the dispersed particles is between those of solution and suspensions. The particle size ranges approximately between 10 Angstrom to 1000 Angstrom in diameter (1 Angstrom = 10^-8 cm). The types of colloids are solid aerosol, sol, solid sol, liquid aerosol, emulsion, solid emulsion, foam, solid foam and gel.

1. Paint (Sol)
2. Fogs (Liquid aerosol)
3. Mayonnaise (Emulsion)
4. Whipped cream (Foam) 5. Marshmallow (Solid Foam)
A Suspension is a heterogeneous mixture in which the solid particles (solute) do not dissolve and instead settle out in a liquid solution.
Examples of suspension are:
1. Milk of magnesia
2. Muddy water 3. Flour in water
4. Slaked lime for whitewashing
5. Mixture of dust particles and
air.
