An inorganic Lewis acid $(X)$ shows in the reaction:
It fumes in moist air:The intensity of fumes increases when a rod dipped in ${NH}_{4} OH$ is brought near it.An acidic solution of $(X)$ on addition of ${NH}_{4} Cl$ and ${NH}_{4} OH$ gives a precipitate which dissolves in $NaOH$ solution:An acidic solution of $(X)$ does not give precipitate with $H_{2} S$ . Identify $(X)$ and give chemical equations for reactions at steps $(i)$ to $(iii)$ .
