Question

Two cells A and B are connected in series to a supply of electricity and 0.04 faraday of electricity are passed through each cell, each cell contains an aqeous solution of copper II tetraoxosulphate VII of the same concentration but cell A has copper electrodes and cell B has platinum electrode what happens at the anode in A and the cathode in B?
Also if cathode A as increased in mass by 1.25g, calculate the mass which would have been deposited by one Faraday of electricity at A.
