Question

1. Electrolysis with a current of 10 A is carried out with 3 kg of molten CuCl. How long (in hours) will it take until 355 g of Cu have been deposited? F = 96500 C mol–1; MCu = 63.5 g mol–1;   MCl =  35.5 g mol–1.

2. During the time taken to deposite the 355 g of Cu from the previous question, what volume of Cl2(g) is released?

T = 298 K P = 1 atms. (molar volume of pure gases at standard state is 24.8 l)
