| Hypophosphorous acid $(H_3PO_2)$ | $+1$ | One $P-OH$,two $P-H$,one $P=O$ |
| Orthophosphorous (Phosphonic) acid $(H_3PO_3)$ | $+3$ | Two $P-OH$,one $P-H$,one $P=O$ |
| Orthophosphoric acid $(H_3PO_4)$ | $+5$ | Three $P-OH$,one $P=O$ |
| Pyrophosphoric acid $(H_4P_2O_7)$ | $+5$ | Four $P-OH$,two $P=O$,one $P-O-P$ |
