Transference numbers of silver perchlorate in water at 25°C

Abstract

The cation and anion transference numbers of aqueous silber perchlorate at 25°C have been determined by the direct moving boundary method from 0.01 to 0.2 M. The cation constituent transference numbers rise in a monotone fashion with increasing concentration contrary to the expectations, of the limiting Debye-Huckel-Onsager theory. The results can be fitted by the revised 1963 Fuoss-Onsager theory only by the assumption of unrealistically large distances of closest approach. The behavior of aqueous silver perchlorate closely parallels that of aqueous silver nitrate and suggests that some property of the silver ion is responsible.
