Answer:
First ionization step:
H₂SeO₄(aq) + H₂O(l) → H₃O⁺(aq) + HSeO₄⁻(aq)
Second ionization step:
HSeO₄⁻(aq) + H₂O(l) → H₃O⁺(aq) + SeO₄⁻²(aq)
Explanation:
Selenic acid is a dyprotic and a strong acid with the formula: H₂SeO₄.
When it reacts to water, it release two protons in two ionizations.
Finally it gives hydronium to the medium.
H₂SeO₄(aq) + H₂O(l) → H₃O⁺(aq) + HSeO₄⁻(aq)
HSeO₄⁻(aq) + H₂O(l) → H₃O⁺(aq) + SeO₄⁻²(aq)
