The balanced net ionic equations: H₂SeO₄(aq) ⇄ 2H+(aq) + SeO₄2-(aq)
First step of balanced chemical dissociation of selenic acid in water:
H₂SeO₄(aq) ⇄ HSeO4⁻(aq) + H⁺(aq)
H₂SeO₄(aq) + H₂O(l) ⇄ HSeO4⁻(aq) + H₃O⁺(aq).
Ka is the acid dissociation constant or equilibrium constant, which quantifies the extent of acid dissociation (in this example selenic acid) in water.
Ka1 = [HSeO4⁻]·[H⁺] / [H₂SeO₄]
or Ka1 = [HSeO4⁻]·[H₃O⁺] / [H₂SeO₄]
Second step of balanced chemical dissociation of selenic acid in water:
HSeO4⁻(aq) ⇄ H+(aq) + SeO₄2-(aq)
Ka2 = [HSeO4⁻]·[H⁺] / [SeO₄2-]; equilibrium constant for second step of dissociation of selenic acid.
