Which process is preferred at the anode during the electrolysis of dilute sulfuric acid?

Options

  1. A2H 2 O(l) → O 2 (g) + 4H+(aq) + 4e-
  2. B2SO 4 2- (aq) → S 2 O 8 2- (aq) + 2e-
  3. C2H 2 (l) → O 2 (g) + 4H+(aq) + 4e-
  4. D2SO 4 2- (aq) → S 2 O 8 2- (aq) + 2e-

Correct answer

A. 2H 2 O(l) → O 2 (g) + 4H+(aq) + 4e-

Step-by-step solution

The preferred process at the anode during the electrolysis of dilute sulfuric acid is 2H 2 O(l) → O 2 (g) + 4H+(aq) + 4e-.
