WebExtended Debye-Huckel Law takes into account the fact ions have size, so it is the limiting law, divided by a correction for the size of the ion. A and B are constante that depend on solvent and temperature. Deviations from the D-H laws at higher concentrations are due to ion-solvent interactions. WebAn exact evaluation is presented of the free energy term which is expected to be the next higher order above the lowest one, the Debye-Huckel law. It is concluded that the Debye-Huckel is exact with respect to the deg F. Cores o order for purely Coulomb interactions as well as for the one with hard cores. (C.J.G.)
WebDebye-Huckel theory limitations The derivation of the equations of the Debye-Huckel theory did not require differentiation between a solution of a single electrolyte and an electrolyte … In organic chemistry, Hückel's rule predicts that a planar ring molecule will have aromatic properties if it has 4n + 2 π electrons, where n is a non-negative integer. The quantum mechanical basis for its formulation was first worked out by physical chemist Erich Hückel in 1931. The succinct expression as the 4n + 2 rule has been attributed to W. v. E. Doering (1951), although several authors were u…
