$Na_2HPO_4$

Vedclass · Answer

(C) salt can furnish $H^{+}$ ions in an aqueous solution if it contains at least one ionizable hydrogen atom directly bonded to an oxygen atom ($-OH$ group).$NaH_2PO_2$ (Sodium hypophosphite) has no $P-OH$ bond,so it cannot furnish $H^{+}$ ions.$Na_2HPO_3$ (Sodium phosphite) has no $P-OH$ bond,so it cannot furnish $H^{+}$ ions.$Na_2HPO_4$ (Disodium hydrogen phosphate) contains a $P-OH$ bond,which allows it to dissociate in water to release $H^{+}$ ions: $Na_2HPO_4 \rightleftharpoons 2Na^{+} + HPO_4^{2-} + H^{+}$.Therefore,only $Na_2HPO_4$ can furnish $H^{+}$ ions.
