Ionic mobility and transport number

WebIonic mobility or Ionic conductance is the conductivity of a solution containing 1 g ion, at infinite dilution, when two sufficiently large electrodes are placed 1 cm apart. Ionic mobilities ( λa or λc) ∝ speeds of ions (ua or uc) Unit of ionic mobility is Ohm–1 cm2 or V–1S-1cm2 Ionic mobility and transport number are related as, WebThe expressions for the equivalent conductivity and the stoichiometric transport numbers are derived using the equivalent fractions, the total equivalent concentration and the conventional ionic conductivities of the ion constituents. Limiting values and limiting laws under several conditions are studied.
