Electrolysis of Sulfuric Acid Quiz

Which ions are present in the aqueous solution of sulfuric acid?

• Na+ and OH-

• K+ and NO3-

• H+ and SO4^2-

• H+ and Cl-

What happens to the H+ ions at the cathode during electrolysis?

• They remain unchanged.

• They form sulfuric acid.

• They are reduced to form hydrogen gas.

• They are oxidized to form water.

Which ion is oxidized at the anode during the electrolysis of sulfuric acid?

• SO4^2-

• H+

• OH-

• Cl-

What is the ratio of hydrogen gas to oxygen gas produced during the electrolysis of sulfuric acid?

• 2:1

• 1:2

• 1:1

• 3:1

Why do sulfates not discharge at the anode during electrolysis?

• They never oxidize at the anode.

• They form a solid precipitate.

• They are not present in the solution.

• They are too reactive.
