Which is a set of acid salts and can react with base?

Acid salts react with bases forming slats and water as per the reaction given below. 

$\begin{array}{l}{\mathrm{NaH}}_2{\mathrm{PO}}_4+\mathrm{NaOH}\to {\mathrm{Na}}_2{\mathrm{HPO}}_4+{\mathrm{H}}_2\mathrm{O};\\ {\mathrm{NaH}}_2{\mathrm{PO}}_3+\mathrm{NaOH}\to {\mathrm{Na}}_2{\mathrm{HPO}}_4+{\mathrm{H}}_2\mathrm{O}\\ {\mathrm{Na}}_2{\mathrm{HPO}}_4+\mathrm{NaOH}\to {\mathrm{Na}}_3{\mathrm{PO}}_4+{\mathrm{H}}_2\mathrm{O}\end{array}$
