In an electrolysis set up consist of a platinum anode and copper cathode, was
used to electrolyze 250 mL of CuSO 4 solution. When the cell was operated
for 0.5 h using 3mA current, the absorbance of the CuSO 4 solution reduced
to 50% percent from its original value. Calculate the initial concentration of
copper sulphate solution.
