Select a pair of amphoteric oxides from the following.

Options

  1. ASO 2 ,   TeO 2
  2. BSO 3 ,   TeO 2
  3. CPoO 2 ,   TeO 2
  4. DTeO 3 ,   TeO 2

Correct answer

C. PoO 2 ,   TeO 2

Step-by-step solution

The oxides SO 2 ,   SO 3 ,   SeO 2 ,   SeO 3 and TeO 3 are acidic, but TeO 2 is amphoteric in nature. The oxide PoO 2 , while amphoteric, even shows some basic character.
