Question

According to Faraday’s second law, the weights of different substances evolved by the passage of the same quantity of electricity are proportional to their _______________

(a) Chemical equivalent weight

(b) Current supply

(c) Chemical equivalent density

(d) Volume

This question was addressed to me by my school teacher while I was bunking the class.

Question is taken from Faraday’s Laws of Electrolysis topic in section Corrosion, Electrolysis, Fuel Cells and Batteries of Engineering Chemistry II

Answer 1

Right answer is (a) Chemical equivalent weight

The best explanation: According to Faraday’s second law, the weights of different substances evolved by the passage of same quantity of electricity are proportional to their chemical equivalent weights. For Faraday’s second law, Q, F, and z are constants, so that the larger the value of M/z (equivalent weight) the larger m will be.
