Question

What current strength in Ampere will be required to produce 2.4g of cu from cuso4 solution in 1 hour ? Molar mass of cu = 63.5 g

Answer 1

Explanation:

Cathode increases in mass as copper is deposited on it and the anode decreases in mass as copper from it dissolves.

Charge passed through cell = I (we have to find).

Hence,

I= 2.4×2×96500/ 63.5×60×60= 2.03A
