Question

A compound $(X)$ on heating with an excess of $N a O H$ solution gives a gas $(Y),$ which gives white fumes on exposure to $H C l$ . Heating is continued to expel the gas completely. The resultant alkaline solution again liberates the same gas $Y$ when heated with $Z n$ powder. However, the compound $(X)$ when heated alone does not give nitrogen. Identify the compounds $X$ and $Y$ .

Solution

Ammonium nitrate $(N H_{4} N O_{3})$ is a white crystalline solid which is highly soluble in water.
Ammonium nitrate reacts with metal hydroxides, releasing ammonia and forming alkali metal nitrate, $N H_{4} N O_{3} + N a O H N H_{3} + H_{2} O + N a N O_{3}$ , the ammonia released reacts with $H C l$ to gives white dense fumes of Ammonium chloride ( $N H_{4} C l$ ).
Ammonium nitrate leaves no residue on heating $N H_{4} N O_{3} N_{2} O + 2 H_{2} O$
