Question

A titraion was performed using H3PO4 to neutrilize (react completly with) NaOH. Write a complete and balanced Neutralized reaction.

Answer 1

H3PO4 Phosphoric acid is a triacidic base and ionizes 3 moles of H+ ions per mole of H3PO4.

Whereas NaOH is monobasic acid i.e.ionizes 1 mole of HO- ion per mole of NaOH.

Hence to Neutralize 1 mole of H3PO4 it takes 3 moles of NaOH,

Hence we write a Balanced Neutralization reaction as,

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

Hence a complete and balanced neutralization reaction.
