 | | This double layer surrounds all charged macromolecules and particles in solution and plays a role in several properties of significance in chemical analysis and processing including (but not limited to): precipitation, flocculation, electrophoresis, colloid stability, phase partitioning, and sorption. |
 | | The shear plane is assumed to be in the diffuse layer, close to the boundary between the fixed and the diffuse layers. |
 | | The Gouy-Chapman (G-C) theory, one of the first, assumes a) a flat, impenetratable surface, b) ions in solution are point charges, c) the surface charge and potential are uniformly distributed upon the surface, and d) the solvent properties (including dielectric constant) are independent of distance from the surface. |
