| Donnan equilibrium | An equilibrium established between a charged, immobile colloid (such as clay, ion exchange resin or cytoplasm) and a solution of electrolyte. Characteristics: ions of like charge to the colloid tend to be excluded, ions of opposite charge tend to be attracted, the colloid compartment is electrically polarized relative to the solution in the same direction as the colloid charges (a Donnan potential) and the osmotic pressure is higher in the colloid compartment. (18 Nov 1997) |

| gibbs-donnan effect | The observation that charged molecules starting on one side of a semipermeable membrane sometimes will not evenly distribute themselves by diffusion on both sides of the membrane. This effect is probably because there are other charged substances already present which cannot move through the membrane themselves and which are creating an electric field that influences the movement of the incoming charged molecules.

| Donnan's equilibrium |
the conditions which exist at equilibrium when two solutions are separated by a membrane permeable to some but not all of the ions of the solutions. There is a complex distribution of the ions between the two solutions, an electrical potential develops between the two sides of the membrane, and the two solutions vary in osmotic pressure. Called also Gibbs-Donnan e.
