The amount of electricity which release 2.0g of gold from a gold salt is same as that which dissolves 0.967g of copper anode during the electrolysis of copper sulphate solution. What is the oxidation number of gold in the gold ion ? (At mass of Cu=63.5,Au=197)

The ion which is discharged at the cathode during the electrolysis of copper sulphate solutions using copper electrodes an anode and cathode ?

If the quantity of electricity required to liberate 2.6267 g of gold from a solution of gold salt is used for the the electrolysis of CuSO_(4) solution in presence of copper anode, then 1.26 g of copper gets dissolved. Find the oxidation number of gold in the gold salt. [Cu=63, Au=197]

The ion which is discharged at the anode during the electrolysis of copper sulphate solution using platinum electrode as anode and cathode [Cu^(2+) OH^(-),SO_(4)^(2-) H^(+)]
