How many of the following oxides are amphoteric? \[ \mathrm{BeO}, \mathrm{ZnO}, \mathrm{Sb}_2 \mathrm{O}_3, \mathrm{CO}, \mathrm{CaO}, \mathrm{SO}_2, \mathrm{SO}_3 \]
- A 2
- B 3
- C 4
- D 5
Answer & Solution
Correct Answer
(B) 3
Step-by-step Solution
Detailed explanation
Amphoteric oxides are oxides that can act as either an acid or base in a reaction to produce a salt and water. \(\mathrm{BeO}, \mathrm{ZnO}\) and \(\mathrm{Sb}_2 \mathrm{O}_3\) are amphoteric oxides.
