WebTo use this online calculator for Debey-Huckel Limiting Law Constant, enter Mean Activity Coefficient (γ±), Charge number of ion species (Zi) & Ionic strength (I) and hit the calculate button. Here is how the Debey-Huckel Limiting Law Constant calculation can be explained with given input values -> 0.024506 = - (ln (0.5))/ (2^2)*sqrt (0.02). 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…

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.
