Question:

For the reaction: I⁻ + ClO₃⁻ + H₂SO₄ → Cl⁻ + HSO₄⁻ + I₂, The correct statement(s) in the balanced equation is/are: stoichiometric coefficient of HSO₄⁻ is 6, iodide is oxidized, sulphur is reduced, H₂O is one of the products

sulphur is reduced

iodide is oxidized

stoichiometric coefficient ofHSO₄⁻ is 6

H₂O is one of the products

Solution:

The balanced equation is ClO₃⁻ + 6I⁻ + 6H₂SO₄ → 3I₂ + Cl⁻ + 6HSO₄⁻ + 3H₂O.
