NaOH + H3PO4 = Na3PO4 + H2O

Balanced Chemical Equation – Solution

3NaOH + H3PO4 → Na3PO4 + 3H2O

The coefficients show the number of particles (atoms or molecules), and the indices show the number of atoms that make up the molecule. New substances are formed as a result of the rearrangement of the original atoms. As a result of a chemical reaction, atoms of chemical elements do not disappear anywhere and new ones do not appear, their number remains unchanged – this follows from the law of conservation of mass of substances.

Chemical Reaction Information

This is an acid-base reaction (neutralization): NaOH is a base, H3PO4 is an acid.

Sodium Hydroxide + Phosphoric Acid = Trisodium Phosphate + Water
