Explain about Debye-Huckel and Onsagar equation.

1.	Explain about Debye-Huckel and Onsagar equation.
Answer» The influence of ion-ion interactions on the conductivity of strong electrolytes was studied by Debye and Huckel. They considered that each ion is surrounded by an ionic atmosphere of opposite sign, and derived an expression relating the molar conductance of strong electrolytes with the concentration by It was further developed by Onsagar. For a uni – univalent electrolyte the Debye Huckel and Onsagar equation is given below. Λ_m = Λ_m° (A + B Λ°m) \(\sqrt{c}\) Where A and B are constants which depend only in the nature of the solvent and temperature.
