Question

How nitrate reacts with ammonia so that it becomes ammonium nitrate?

Answer 1

The industrial production of ammonium nitrate entails the acid-base reaction of ammonia with nitric acid: HNO3 + NH3 → NH4NO. Ammonia is used in its anhydrous form (i.e., gas form) and the nitric acid is concentrated. ... The ammonia required for this process is obtained by the Haber process from nitrogen and hydrogen.
