Chemistry - Ionic Equilibrium Question with Solution | TestHub

A piece of aluminium was dissolved in 11.2 g of KOH , till KOH is completely reacted. The solution is filtered, neutralized by dil. ${\mathrm{H}}_2{\mathrm{SO}}_4$. Crystallization of this solution gave a compound $(\mathrm{X})$. When the aqueous solution of $(\mathrm{X})$ is treated with ${\mathrm{BaCl}}_2$ solution 9.32 gm of white precipitate is formed. What is the weight of aluminium metal dissolved in KOH . (atomic weights of $\mathrm{Al}=27,\mathrm{Ba}=137,\mathrm{S}=32,\mathrm{O}=16,\mathrm{K}=39$, and $\mathrm{Cl}=35.5$ )
