The amphoteric oxide among

\mathrm{V}_2 \mathrm{O}_3, \mathrm{~V}_2 \mathrm{O}_4

and

\mathrm{V}_2 \mathrm{O}_5

, upon reaction with alkali leads to formation of an oxide anion. The oxidation state of V in the oxide anion is :

Accepted Answer

$\begin{aligned} V_{2} O_{5} + alkali \to {VO}_{4}^{3 -} \\ In {VO}_{4}^{3 -} ion, vanadium is in + 5 oxidation state \end{aligned}$
