When platinum electrodes are used during the (I) electrolysis of cooper (II) tetraoxoxulphate (V) Solution, the solution gets progressively
A. Acidic B. Basic C. Neutral D. Atmospheric
Correct Answer: A
Explanation
\(Cu ^{2+}\) is preferentially discharged at the cathode, \(Cu ^{2+}\) being lower than \(H ^{+}\)in the activity series. At the anode, \(OH\)-preferentially discharges; liberating \(O _{2}\) and leaving the solution with excess \(H ^{+}\)which increases the level of acidity at the anode.
