Wired Faculty App

How is molar conductivity related to the degree of dissociation?

Solution

Answer:
At any concentration c, if a is the degree of dissociation then it can be approximated to the ratio of molar conductivity Ëm at the concentration c to limiting molar conductivity, Ëm°. Thus we have

Λ_m and degree of dissociation (a) are related by the equation

α = \frac{{A^{c}}_{m}}{{A^{\infty}}_{m}}
