Write the equation for the reaction associated with the ka2 of sulfuric acid h2so4

Chemical reaction: HSO₄⁻ (aq) ⇄ H⁺ (aq) + SO₄²⁻ (aq);

or HSO₄⁻ (aq) + H₂O (l) ⇄ H₃O⁺ (aq) + SO₄²⁻ (aq)

Ka₂ = [H⁺]·[SO₄²⁻]/[HSO₄⁻]; Ka₂ = 1.0·10⁻².

[H⁺] is equilibrium concentration of hydrogen cations.

[SO₄²⁻] is equilibrium concentration of sulfate anions.

[HSO₄⁻] is equilibrium concentration of hydrogensulfate (bisulfate) anions.
