A certain compound X impats golden yellow flame. Whenzinc powder is heated with concenrated solution of X, H_(2) gas is evolved. X combines with CO_(2) to give a salt Y. Y is a hydrated salt which on reaction with HCl or ecess of CO_(2) gives another salt Z which is an important part of baking powder. identify X, Y and Z.

1.	A certain compound X impats golden yellow flame. Whenzinc powder is heated with concenrated solution of X, H_(2) gas is evolved. X combines with CO_(2) to give a salt Y. Y is a hydrated salt which on reaction with HCl or ecess of CO_(2) gives another salt Z which is an important part of baking powder. identify X, Y and Z.
Answer» `X-NaOH,Y-Na_(2)CO_(3),Z-NaHCO_(3)` `X-HCl, Y-NaOH,Z-NaHCO_(3)` `X-KOH,Y-K_(2)CO_(3),Z-KHCO_(3)` `X-NACL,Y-Na_(2)CO_(3),Z-NaOH` SOLUTION :`Zn+UNDERSET((X))(2NAOH) to Na_(2)ZnO_(2)+H_(2)` `underset((X))(2NaOH)+CO_(2)tounderset((Y))(Na_(2)CO_(3))+H_(2)O` `underset((Y))(Na_(2)CO_(3))+HCl to underset((Z))(NaHCO_(3))+NaCl` ltBrgt `underset((Y))(Na_(2)CO_(3))+CO_(2)+H_(2)O to underset((Z))(2NaHCO_(3))`
