H2 (g) E∘=0.00V
(III) 2SO42−(aq)→S2O82−(aq)+2e−E∘=1.96V
(a) In dilute H2SO4 Solution, H+ions are reduced at cathode.
(b) In concentrated H2SO4 solution, water is oxidized at anode.
(c) In dilute H2SO4 solution, water is oxidised at anode.
(d) In dilute H2SO4 solution, SO42− ions are oxidized at anode.
