Question:

What are the product of Electrolysis of dilute H2SO4 using inert electrodes at cathode and anode respectively?

Options:

O2 and SO2

SO2 and O2

O2 and H2

H2 and O2

Correct Answer:

H2 and O2

Explanation:

H2SO⇔ 2H+ + SO42-

H2O ⇔ H+ + OH-

At anode: 2OH- → H2O + \(\frac{1}{2}\)O2 + 2e-

At cathode: 2H+ + 2e- → H2
