Question

The electric charge for electrode deposition of one gram equivalent of a substance is:

• A. one ampere per second
• B. $96,500$ coulombs per second
• C. one ampere for one hour
• D. charge on one mole of electrons

Answer 1

The correct option is D charge on one mole of electrons

According to the Faraday's First Law of Electrolysis, “The mass of a substance deposited at any electrode is directly proportional to the amount of charge passed.”
$⟹$ One gram equivalent of an electrolyte required $1.0mole$ of electronic charge for discharging.
