MCQ
Which of the following oxide is amphoteric ?
- ✓$SnO_2$
- B$CaO$
- C$SiO_2$
- D$CO_2$
✓
Answer
Correct option: A.
$SnO_2$
a
$\mathrm{SnO}_{2}$ react with acid as well base
$\mathrm{SnO}_{2}$ react with acid as well base
So amphoteric
$\mathrm{SnO}_{2}+4 \mathrm{HCl} \longrightarrow \mathrm{SnCl}_{4}+2 \mathrm{H}_{2} \mathrm{O}$
$\mathrm{SnO}_{2}+2 \mathrm{NaOH} \longrightarrow \mathrm{Na}_{2} \mathrm{SnO}_{3}+\mathrm{H}_{2} \mathrm{O}$
