Ionic Transport in Water and Mixed Aqueous Solvents
The mechanism of ionic transport was one of the earliest problems to interest the physical chemist. This early interest resulted not only from the intrinsic importance of the problem but also from a number of important developments before the turn of the last century. The Arrhenius theory(26) established the dissociated nature of electrolytic solutions and precise methods for the measurement of both conductances(456) and transference numbers(378) were developed quite early. The introduction of transference data was the most significant contribution since they permitted an unambiguous split into ionic conductances to be made and thereby allowed comparisons between anions and cations and between all ions at different temperatures and pressures. Until very recently ionic mobilities were the only ionic property that could be obtained independent of any arbitrary split.†
