Q. Copper sulphate solution (250ml) was electrolysed using a platinum anode and a copper cathode. A constant current of 2mA was passed for 16 minutes. It was found that after electrolysis, the absorbance of the solution was reduced to 50% of its original value. Calculate the concentration of copper sulphate in the solution to begin with.
