1.	When an aqeous solution of copper (II) sulphate is electrolysed between two copper electrodes , the blue colour ions are discharged and deposited as metallic copper at cathode . But the blue colour of the solution does not fade . Explain.
Answer» Solution :Because as the `Cu^(2+)` ions are reduced at the cathode at the same TIME equal NUMBER of `Cu^(2+)` ions are produced by the oxidation of anodic COPPER . (a) `Cu^(2+) + 2E^(-) to Cu` (b) `Cu to Cu^(2+) +2e^(-)`
