Pyrophosphoric acid contains two $P-H$ bonds

Vedclass · Answer

(C) The chemical formula of pyrophosphoric acid is $H_4P_2O_7$. It has a structure with one $P-O-P$ linkage, four $P-OH$ bonds, and two $P=O$ bonds. Since it has four $P-OH$ groups, it is a tetrabasic acid. It does not contain any $P-H$ bonds. Orthophosphoric acid $(H_3PO_4)$ is prepared by dissolving $P_4O_{10}$ in water: $P_4O_{10} + 6H_2O \longrightarrow 4H_3PO_4$. Therefore, the statement that pyrophosphoric acid contains two $P-H$ bonds is incorrect.
