## Question:

Write a net ionic equation for the overall reaction that occurs when aqueous solutions of phosphoric acid and potassium hydroxide are combined. Assume excess base.

## Neutralization Reaction:

There is no definite manifestation for a neutralization reaction because there are so many types of acids and bases that can exhibit this type of reaction. It can be that an adduct is formed or the conjugates are produced. Either way, it will still be considered a neutralization reaction as long as it is between an acid and a base.

The molecular equation for the reaction between phosphoric acid and potassium hydroxide is:

{eq}\rm H_3PO_4(aq) + 3KOH(aq) \to 3H_2O(l) + K_3PO_4(aq) {/eq}

The full ionic equation from this is:

{eq}\rm 3H^+(aq)+PO_4^{3-}(aq) + 3K^+(aq)+ 3OH^-(aq) \to 3H_2O(l) + 3K^+(aq)+ PO_4^{3-}(aq) {/eq}

Based on the reaction above and removing the spectator ions (same on both sides), the net ionic equation is:

{eq}\rm 3H^+(aq) + 3OH^-(aq) \to 3H_2O(l) {/eq}
