Which pair of electrolytes cannot be distinguished by the products of electrolysis using inert electrodes?

A

1M `CuSO_(4)` solution, `1M CuCl_(2)` solution

B

1M KCl solution, 1M KI solution

C

1 M `AgNO_(3)` solution `1M Cu(NO_(3))` solution

D

1M `CuBr_(2)` solution `1M CuSO_(4)` solution.

Text Solution

Verified by Experts

The correct Answer is:
A
(A) `CuSO_(4)rarrCu+O_(2):CuCl_(2)rarrCu+I_(2)`
(B) `KClrarrH_(2)+Cl_(2):KIrarrH_(2)+I_(2)`
(C) `AgNO_(3)rarrAG+O_(2),:NaClrarrH_(2)+Cl_(2)`
(D) `KClrarrH_(2)+Cl_(2):NaClrarrH_(2)+Cl_(2)`
(E) `CuBrrarrCu+Br_(2):CuSO_(4)rarrCu+O_(2)`
Thus KCl and NaCl solution give the same products at anode and cathode.
