PO 43-, oxidation no. of P ⇒ +5 SO 42-, oxidation no. of S ⇒ +6 Cr 2 O 72-, oxidation no. of Cr ⇒ +6

Q. Oxidation numbers of P in $P O_{4}^{3 -}$ , of $S$ in $S O_{4}^{2 -}$ and that of $C r$ in $C r_{2} O_{7}^{2 -}$ respectively are

+5, +6 and +6

+3, +6 and +5

+5, +3 and +6

-3, +6 and +6 17 18 19

$P O_{4}^{3 -}$ , oxidation no. of $P \Rightarrow + 5$

$S O_{4}^{2 -}$ , oxidation no. of $S \Rightarrow + 6$

$C r_{2} O_{7}^{2 -}$ , oxidation no. of $C r \Rightarrow + 6$
