Answer: Balanced net ionic equation is [tex]3H^{+}(aq)+3OH^{-}(aq)\rightarrow 3H_2O(l)[/tex]
Explanation:
Neutralization is a chemical reaction in which an acid and a base reacts to form salt and water.
Spectator ions are defined as the ions which does not get involved in a chemical equation or they are ions which are found on both the sides of the chemical reaction present in ionic form.
The given chemical equation is:
[tex]H_3PO_4(aq)+3NaOH(aq)\rightarrow Na_3PO_4(aq)+3H_2O(l)[/tex]
The ions which are present on both the sides of the equation are sodium and phosphate ions and hence are not involved in net ionic equation is:
[tex]3H^{+}(aq)+3OH^{-}(aq)\rightarrow 3H_2O(l)[/tex]
