The limiting ionic conductance of Li + in water is less than that of Na + ,

Question:

The limiting ionic conductance of Li+ in water is less than that of Na+, which in turn is less than that of K+, a trend believed to be caused by changes in the degree of hydration of the ions. Assuming λ0+ = λ0- in Eq. (17.33), calculate Dv and VA for Li+ nH2O and Na+·nH2O and estimate the values of n. The radius of Li+ is 0.6 Â; that of Na+ is 0.95 Â.

Eq. 17.33D = 13.26 x 10-5 11.140.589 (17.33)
