Explain about Debye-Huckel and Onsager equation.

Explanation

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 assuming complete dissociations.
It was further developed by Onsager. For a uni-univalent electrolyte the Debye Huckel adn Onsagar equation is given below.
`Lambda_m = Lambda_m^@ - (A + B Lambda_m^@) sqrt(c )`
Where A and B are constants which depend only in the nature of the solvent and temperature.
