A current of 12 A is passed through an electrolytic cell containing aqueous

\mathrm{NiS}{\mathrm{O}_4}

solution. Both Ni and

{\mathrm{H}_2}

gas are formed at the cathode. The current efficiency is 60%. What is the mass of nickel deposited on the cathode per hour?

View answer and explanation

Correct option: A

7.883 g

Option A (7.883 g) is correct because the mass of nickel deposited is calculated considering the current efficiency and Faraday's laws.
