Colloid chemistry has been defined as "the chemistry of the infinitely little." It can perhaps be better defined as the chemistry of films, surfaces, and interfaces, for the peculiar energies which are available for the reactions of colloid chemistry are those energies which are characteristic of surfaces and interfaces.
For purposes of classification it has been rather generally agreed that particles which range from 1.0 mµ to 0.5 mµ lie within the colloid realm, and the reactions which such systems show can in the last analysis be traced to reactions which are induced by a decrease in the free energy
