Select the correct statement(s) about electrolysis of aqueous CuSO4 solution.
  • a)
    Anodic reaction is 2H2O(l) → 4H+(aq) + O2(g) + 4e-
  • b)
    Cathodic reactions 2Cu2+ (aq) + 4e- → 2Cu(s)
  • c)
    Due to the deposition of Cu at the cathode,this is the basis of electroplating of copper
  • d)
    Blue colour of the solution fades
Correct answer is option 'A,B,C,D'. Can you explain this answer?
Verified Answer
Select the correct statement(s) about electrolysis of aqueous CuSO4 so...
(a) 
Oxidation takes place at anode - correct
2H2O(l) →4H+ (aq) + O2(g) + 4e-
(b) Reduction take place at cathode - correct
since, E0cell < 0, in electrolysis.
Cell reaction is spontaneous.
(c) Copper is deposited at the cathode, hence the meted to be electroplated (say Fe), should be made cathode - correct (d) Since. Cu2+(aq)- (blue) is reduced Cu(s), hence blue colour fades - correct.
