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 _______.
- A \(+3\)
- B \(+4\)
- C \(+7\)
- D \(+5\)
Answer & Solution
Correct Answer
(D) \(+5\)
Step-by-step Solution
Detailed explanation
\(\mathrm{V}_2 \mathrm{O}_5\) is amphoteric oxide. \(\mathrm{V}_2 \mathrm{O}_5\) gives \(\mathrm{VO}_4{ }^{3-}\) on reaction with alkali oxidation state of V in \(\mathrm{VO}_4{ }^{3-}=+5\)
