Which of the following is an amphoteric oxide?
- A \( \mathrm{V}_{2} \mathrm{O}_{5}, \mathrm{Cr}_{2} \mathrm{O}_{3} \)
- B \( \mathrm{Mn}_{2} \mathrm{O}_{7}, \mathrm{Cr}_{2} \mathrm{O}_{3} \)
- C \( \mathrm{CrO}, \mathrm{V}_{2} \mathrm{O}_{5} \)
- D \( \mathrm{V}_{2} \mathrm{O}_{5}, \mathrm{~V}_{2} \mathrm{O}_{4} \)
Answer & Solution
Correct Answer
(A) \( \mathrm{V}_{2} \mathrm{O}_{5}, \mathrm{Cr}_{2} \mathrm{O}_{3} \)
Step-by-step Solution
Detailed explanation
Amphoteric oxides are those which react with both acids aswell as bases \( \mathrm{V}_{2} \mathrm{O}_{s} \) and \( \mathrm{Cr}_{2} \mathrm{O}_{3} \) are amphoteric oxides.
