$\displaystyle \mathrm{Al}_2 \mathrm{O}_3$ was leached with alkali to get $\displaystyle X$. The solution of $\displaystyle X$ on passing of gas $\displaystyle Y$, forms $\displaystyle Z$. X, Y and Z respectively are :
Official answer
(4)
$\displaystyle \mathrm{X}=\mathrm{Na}\left[\mathrm{Al}(\mathrm{OH})_4\right], \mathrm{Y}=\mathrm{CO}_2, \mathrm{Z}=\mathrm{Al}_2 \mathrm{O}_3 . x \mathrm{H}_2 \mathrm{O}$
