The kind of reaction depicted by the equation is a double displacement reaction.
In double displacement reactions, two ionic compounds that form the reactant exchange anions and cations to form products.
Considering the equation of reaction:
[tex]3 NaBr + H_3PO_4 ---> Na_3PO4 + 3 HBr[/tex]
Na atoms in NaBr were displaced by H atoms in H3PO4 to produce HBr. Also, the displaced Na atoms teamed up with PO4 to form Na3PO4. In other words, the two reactants exchanged their anions/cations to arrive at products.
