The Transport Numbers of the Ions in Solutions of Silver ...

Transport Number of Ions 441 dissociated into the long-chain ion and the simple ion of opposite sign (contra-ion or gegenion). Over the second range the conductivity falls extremely rapidly to about one-half its initial value. This rapid fall was discovered by McBain for solutions of -the soaps and he attributed it to depression of ionization.

Transport Number | Article about Transport Number by …

The transport number is equal to the ratio of the velocity, or mobility, of a given ion to the sum of the velocities, or mobilities, of the cation and anion. It is a characteristic dependent on the mobilities of all the ions in the electrolytic solution, on the concentrations of the ions, and on the temperature of the solution.
