Ammonia from ammonium nitrate
Explanation:
- The compound which are liberating ammonia on heating are ammonium carbonate, ammonium chloride and ammonium sulphate.
- Ammonium sulphate decomposes upon heating above 250°c, first forming ammonium bisulfate.
- Heating at higher temperature results in decomposition into ammonia, nitrogen, sulfur dioxide, and water.
- As a salt of a string acid () and weak base (), its solution is acidic; pH of 0.1 M solution is 5.5
- When an ammonium salt is warmed with sodium hydroxide solution, ammonium gas is evolved.
- Ammonium, is in equilibrium with its ionized form, in aqueous solution.
- When ammonium nitrate is heated, it decomposes exothermically into nitrogen oxide and water.
