Answer:
H⁺(aq) + OH⁻(aq) = H₂O(l)
Explanation:
To find the net ionic equation start by finding the balanced equation.
2HClO₄(aq) + Ba(OH)₂(aq) ⇒ 2H₂O(l) + Ba(ClO₄)₂(aq)
Then put it into the ionic equation.
2H⁺(aq) + 2ClO₄(aq) + Ba²⁺(aq) + 2OH⁻(aq) ⇒ 2H₂O(l) + Ba²⁺(aq) + 2ClO₄(aq)
Remove all the ions that do not change.
2H⁺(aq) + 2OH⁻(aq) ⇒ 2H₂O(l)
And reduce to the lowest common coefficient.
H⁺(aq) + OH⁻(aq) = H₂O(l)
