An aq. Solution of a salt (x) is alkaline to litmus. On strong heating, it swell up to give a glassy material. When conc. `H_(2)SO_(4)` is added to a concentrated solution of x, white crystal of a weak acid separates out. Hence compound (x) is

Aqueous solution of a salt (Y) is alkaline to litmus. On strong heating it swells-up to give a glassy material .When conc H_(2)SO_(4) in added to a hot concentrated solution of (Y) white crystals of a weak acid separate out .Hence , the compound (Y) is

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