Write the overall, ionic and net ionic equations for the following reaction. Perchloric acid (HClO4) and barium hydroxide (Ba(OH)2)

The reaction of perchloric acid and barium hydroxide yields to barium perchlorate (Ba(ClO4)2) and water (H2O). The resulting balanced equation is 2 HClO4 + Ba(OH)2 = Ba(ClO4)2 +2 H2O. This means, for every mole of barium perchlorate produced, 2 moles of perchloric acid and barium hydroxide are required.

Answer : The net ionic equation will be,

[tex]2H^+(aq)+2OH^-(aq)\rightarrow 2H_2O(l)[/tex]

Explanation :

In the net ionic equations, we are not include the spectator ions in the equations.

Spectator ions : The ions present on reactant and product side which do not participate in a reactions. The same ions present on both the sides.

The given balanced ionic equation will be,

[tex]2HClO_4(aq)+Ba(OH)_2(aq)\rightarrow Ba(ClO_4)_2(aq)+2H_2O(l)[/tex]

The ionic equation in separated aqueous solution will be,

[tex]2H^+(aq)+2ClO_4^-(aq)+Ba^{2+}(aq)+2OH^-(aq)\rightarrow 2H_2O(l)+Ba^{2+}(aq)+2ClO_4^-(aq)[/tex]

In this equation, [tex]ClO_4^-\text{ and }Ba^{2+}[/tex] are the spectator ions.

By removing the spectator ions from the balanced ionic equation, we get the net ionic equation.

The net ionic equation will be,

[tex]2H^+(aq)+2OH^-(aq)\rightarrow 2H_2O(l)[/tex]
