What do you observe when electrolysis of copper sulphate is done using strip as anode ? Give reasons.

Answer»

Solution :Electrolyte: `CuSO_(4)`
`CuSO_(4) hArr Cu^(2+) + SO_(4)^(2-)`
`{:("Cathode (reduction)","Anode (Fe) OXIDATION"),(Cu^(2+) + 2E^(-) rarr Cu,Fe - 2e^(-) rarr Fe^(2+)),(,"Compared to " SO_(4)^(2+)"," Fe " ionsies to give " Fe^(2+) " DUE to low reduction potential"):}`
`:. Cu and Fe^(+2)` are PRODUCTS at cathode and anode, respectively.
