Question

The mass of the substance deposited when one Faraday of charge is passed through its solution is equal to

• A. relative equivalent weight
• B. gram equivalent weight
• C. specific equivalent weight
• D. None of the above

Answer 1

Answer: (B)

The mass of the substance deposited when one Faraday of charge is passed through its solution is equal to gram equivalent weight. For example, when one Faraday of charge is passed through $AgN{O}_3$ solution, $108g$ of silver is deposited at the cathode. One Faraday of charge corresponds to one mole of electrons.
