In electrolytic cell external source of voltage is used to bring about a chemical change One of the simplest electrolytic cell consists of two copper strips dipping in an aqueous solution of copper sulphate If a DC voltage is supplied to the two electrodes then copper ions are deposited on the cathode While at anode Cu is converted to Cu aq At cathode Cu aq Cu s Cu s Cu aq At anode Cu 20 g strip of impure copper and 10 g strip of pure copper are dipped in 2 L 0 1 M CuSO4 aq solution 100 A current is passed for 241 25 s through the solution to cause electrolysis Efficiency of current is 80 Answer the following question based on above stem Cu 63 5 g mol Q What is the total weight of pure copper at cathode after the electrolysis
