Question
$\mathrm{Al}_2 \mathrm{O}_3$ was leached with alkali to get $X$. The solution of $X$ on passing of gas $Y$, forms $Z . X, Y$ and $Z$ respectively are
Select the correct option:
A
$\mathrm{X}=\mathrm{Na}\left[\mathrm{Al}(\mathrm{OH})_4\right], \mathrm{Y}=\mathrm{SO}_2, \mathrm{Z}=\mathrm{Al}_2 \mathrm{O}_3$
B
$\mathrm{X}=\mathrm{Na}\left[\mathrm{Al}(\mathrm{OH})_4\right], \mathrm{Y}=\mathrm{CO}_2, \mathrm{Z}=\mathrm{Al}_2 \mathrm{O}_3 . \times \mathrm{xH}_2 \mathrm{O}$
C
$\mathrm{X}=\mathrm{Al}(\mathrm{OH})_3, \mathrm{Y}=\mathrm{CO}_2, \mathrm{Z}=\mathrm{Al}_2 \mathrm{O}_3$
D
$\mathrm{X}=\mathrm{Al}(\mathrm{OH})_3, \mathrm{Y}=\mathrm{SO}_2, \mathrm{Z}=\mathrm{Al}_2 \mathrm{O}_3 . \mathrm{xH}_2 \mathrm{O}$
