Problem
In an electrolysis experiment, current was passed for 5 hour through two cells connected in series. The first cell contains a solution of gold and the second contains CuSO4 solution. 9.85 g of gold was deposited in the first cell. If the oxidation no. of gold is +3, find the amount of Cu deposited on cathode in second cell. Also calculate the current strength in ampere. Atomic mass of Au = 197 and atomic mass of Cu = 63.5.
