Write the balanced ka and kb reactions for hso3 - in water. be sure to include the physical states of each species involved in the reaction.

HSO₃⁻ is amphoteric compound (in this reactions is ion that can react both as an acid and as a base).

When HSO₃⁻ acts as acid, it gives protons to water:

HSO₃⁻ (aq) + H₂O (l) ⇄SO₄²⁻ (aq) + H₃O⁺ (aq).

Ka = [SO₄²⁻] · [H₃O⁺] / [HSO₃⁻].

When HSO₃⁻ acts as base, it accepts protons from water:

HSO₃⁻ (aq) + H₂O (l) ⇄ H₂SO₄ (aq) + OH⁻ (aq).

Kb = [H₂SO₄] · [OH⁻] / [HSO₃⁻].
