3 oct 2013 · In 1923 Peter Debye and Erich Hückel developed an expression that allows one to calculate activity coefficients The extended Debeye-Hückel equation indicates that γ depends on three factors where z is the charge on the ion; α is the hydrated ion radius (in pm); μ is the ionic strength of the solution
