Question

Identify the basic oxide from the following

• A. Cr$_2$O$_3$
• B. CrO$_3$
• C. V$_2$O$_5$
• D. V$_2$O$_3$

Hint:

Transition metal oxides show different behaviors. Lower oxidation states tend to form basic oxides, while higher oxidation states form acidic oxides.

Answer 1

The Correct Option is D

Step 1: Identifying the nature of oxides.
- Cr$_2$O$_3$ is amphoteric.
- CrO$_3$ is acidic.
- V$_2$O$_5$ is acidic.
- V$_2$O$_3$ is basic.
