I had been asked this question in an interview for job.

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

Answer 1

Correct choice is (b) Weight

For explanation I would say: Electrochemical equivalent may be defined as the weight of the substance deposited by the passage of 1 coulomb of electricity. The electrochemical equivalent of an element is measured with a voltameter.
