Which reaction is preferred at the anode for higher concentrations...
Which reaction is preferred at the anode for higher concentrations of sulfuric acid (H2SO4)?
Options
- A2H2O(l) → O2(g) + 4H+(aq) + 4e-
- B2SO (aq) → S2O82- (aq) + 2e-
- C2H2(l) → O2(g) + 4H+(aq) + 4e-
- D2SO42- (aq) → S2O82- (aq) + 2e-
Correct answer
D. 2SO42- (aq) → S2O82- (aq) + 2e-
Step-by-step solution
For higher concentrations of sulfuric acid (H2SO4), the preferred reaction at the anode is 2SO42- (aq) → S2O82- (aq) + 2e-.
