Vedclass · Answer

(C) To find the oxidation state of $V$ in $VO^{2+}$: Let the oxidation state be $x$. Since the charge on oxygen is $-2$,we have $x + (-2) = +2$,which gives $x = +4$. In $VO_2^+$,$x + 2(-2) = +1 \implies x = +5$. In $V(OH)_4^+$,$x + 4(-1) = +1 \implies x = +5$. In $[VO_3 \cdot OH]^{2-}$,$x + 3(-2) + (-1) = -2 \implies x - 7 = -2 \implies x = +5$. Thus,$VO^{2+}$ is the only ion where vanadium is in the $+IV$ oxidation state.

Each of the following ions contains vanadium in the $+V$ oxidation state except:
