Q. The order of the oxidation state of the phosphorus atom in $H_3PO_2, \, H_3PO_4,\, H_3PO_3$, and $H_4P_2O_6$ is
Solution:
Species
Oxidation state of P
$H _{3} PO _{4}$
$+5$
$H _{4} P _{2} O _{6}$
$+4$
$H _{3} PO _{3}$
$+3$
$H _{3} P O_{2}$
$+1$
| Species | Oxidation state of P |
|---|---|
| $H _{3} PO _{4}$ | $+5$ |
| $H _{4} P _{2} O _{6}$ | $+4$ |
| $H _{3} PO _{3}$ | $+3$ |
| $H _{3} P O_{2}$ | $+1$ |
