Question

Which of the following statements is true regarding ionic speed?

(a) It is independent of the size of the ion

(b) It depends on the potential difference between the two electrodes

(c) It is independent of the concentration of the electrolyte

(d) It is independent of the charge of the ion

I got this question in an interview.

My question is from Conductance of Electrolytic Solutions topic in chapter Electrochemistry of Chemistry – Class 12

Answer 1

The correct choice is (b) It depends on the potential difference between the two electrodes

Easy explanation: Ionic speed is the speed with which the ion moves in the electrolyte during current passage. It depends on the nature of the ions, potential difference, separation between the electrodes and the concentration of the electrolyte. The ionic speed is directly proportional to the potential difference between the electrodes.
