A certain salt `(X)` gives the following tests :  (a) Its aqueous solution is alkaline to litmus.  (b) On strong heating. It sweels to give a glassy bead.  ( c) When conc `H_(2) SO_(4)` is added to a hot concentrated solution of `(X)`, white crystals of  a weak acid separates out. Identify `(X)` and write down the chemical equations for reaction at steps `a, b` and `c`.
