Question

Which of the following is not a necessary condition for the
preferential discharging of ions?

A. The concentration of the ions
B. The distance between the electrodes
C. The nature of ions
D. The type of electrode used

Answer 1

Selective discharge of ions depends on three factors :

(a) The relative position of ions in the electrochemical (activity) series.

(b) The relative concentration of ions.

(c) The nature of the electrodes.

So,it does not depend on distance between electrodes.(option B)
