Question

The unit of ionic mobility in SI system is ____________

(a) msV^-1

(b) m^3sV^2

(c) m^2s^-1V^-1

(d) m^2s^-1V

I had been asked this question in semester exam.

I need to ask this question from Faraday’s Laws of Electrolysis in portion Corrosion, Electrolysis, Fuel Cells and Batteries of Engineering Chemistry II

Answer 1

The correct answer is (c) m^2s^-1V^-1

Easiest explanation: The unit of ionic mobility in SI system is m^2s^-1V^-1. The separation of ions according to their mobility in gas phase is called ion mobility spectrometry, in liquid phase it is called electrophoresis.
