1.	A solution of a colourles salt H on boiling with excess of NaOH produces a non-flammable gas and the evolution of gas ceases after sometime. Upon addition of Zn dust to the same solution, the evolution of gas restarts. The colourless salt (S) 'H' is (are)
Answer» `NH_(4)NO_(3)` `NH_(4)NO_(2)` `NH_(4)Cl` `(NH_(4))_(2)SO_(4)` Solution :The COLOURLESS SALTS are `NH_(4)NO_(3)` (a) and `NH_(4)NO_(2)` (B). `underset((a))(Na_(4)NO_(3)) + NaOH rarr NaNO_(3) + underset(("Colourless gass"))(NH_(3) + H_(2)O)` `NaNO_(3) + 8[H] overset((Zn - "dust"))rarr NaOH + NH_(3) + 2H_(2)O` `underset((b))(NH_(4)NO_(2)) + NaOH rarr NaNO_(2) + NH_(3) + H_(2)O` `NaNO_(2) + 6[H] overset((Zn - "dust"))rarr NaOH + NH_(3) + H_(2)O`
