Question

(b) How transport number depends upon lonic mobility?​

Answer 1

Explanation:

It depends on the movement of the boundary between two adjacent electrolytes under the influence of an electric field. If a colored solution is used and the interface stays reasonably sharp, the speed of the moving boundary can be measured and used to determine the ion transference numbers

Answer 2

Answer:The transport number is usually determined by the Hittorf method—that is, by the change in the concentrations of the ions near the electrodes. During electrolysis, ions, owing to solvation, transport not only electric charge but also the solvent in their solvation sheaths. For this reason, transport numbers determined by the Hittorf method are called apparent transport numbers—in contrast to true transport numbers, which take into account only the velocities of the ions.
