With respect to tje electrolysis of copper (II) sulphate soltn.usong copper electrodes answer the following
1. What do you observe at the cathode and at the anode.
2. What change is noticed in the electrolyte.??
3.write the reactions at the cathode and at the anode.

Dear student,
 Here the anode used is impure copper. The electrolyte  copper sulphate can dissolve the impure copper and produce Cu2+which is attracted towards cathode. This will result in the accumulation of Cu2+ over cathode. Here the cathode used is pure copper.
The cathode become thicker and the anode become thinner.
The copper sulphate solution will become muddy because of the impurities.
At cathode: reduction occurs
Cu2++2e gives Cu
At anode: oxidation occurs
Cu gives Cu2++2e

The electrolysis of aqueous copper sulphate is used for purification of impure copper. During electrolysis the impure copper is used as anode and pure copper is used as cathod . The electrolyte copper sulphate is to dissolve impure copper which produce Cu⁺² that migrate towards cathode and deposit over pure copper (cathode). At Anode : Cu (s) → Cu⁺²(aq) + 2 e⁻ At cathode : Cu⁺²(aq) + 2 e⁻ → Cu (s)

1. The cathode becomes thicker due to deposition of pure copper whereas anode gets thinner due to dissolving of impure copper into electrolyte. 2.The electrolyte solution becomes dirty due to dissolving of impure copper metal. Also the insoluble impurities are seen to deposit below the anode as "anode mud". 3.
