Write a net ionic equation for the overall reaction that occurs when aqueous solutions of...

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}
