Question

Write the balanced equations for the neutralization of phosphoric acid with NaOH.

molecular equation:

ionic equation:

net ionic equation:

Answer 1

molecular equation is:

H₃PO₄ (aq) + 3 NaOH (aq) --> Na₃PO₄ (aq) + 3 H₂O (l)

To get complete ionic equation, break aqueous components into respective ions

So, the complete ionic equation is

3 H⁺ (aq) + PO₄^3- (aq) + 3 Na⁺ (aq) + 3 OH^- (aq) --> 3 Na⁺ (aq) + PO₄^3- (aq) + 3 H₂O (l)

To get net ionic equation, remove the common ions from both sides

So, the net ionic equation is

H⁺ (aq) + OH^- (aq) --> H₂O (l)
