A current of strength 2.5 A was passed through

\mathrm{CuS}{\mathrm{O}_4}

solution for 6 min 26 s. The amount of copper deposited is (At. Wt. of Cu = 63.5, 1F = 96500 C)

View answer and explanation

Correct option: A

0.3175 g

Option A (0.3175 g) is correct because the mass of copper deposited is calculated using Faraday's laws, relating current, time, and the electrochemical equivalent of copper.
