Question

Write out the BALANCED NET IONIC equation for the neutralization reaction that occurs between aqueous phosphoric acid and aqueous sodioum hydroxide. Include all states of matter.

Answer 1

Answer: Balanced net ionic equation is $3H^{+}(aq)+3OH^{-}(aq)\rightarrow 3H_2O(l)$

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:

$H_3PO_4(aq)+3NaOH(aq)\rightarrow Na_3PO_4(aq)+3H_2O(l)$

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:

$3H^{+}(aq)+3OH^{-}(aq)\rightarrow 3H_2O(l)$
