Chemistry
State a reason why reaction of liquor ammonia with nitric acid is a neutralization reaction.
Answer
As liquor ammonia is an alkali due to the presence of hydroxyl ions.
NH3 + H2O ⟶ NH4OH
NH4OH ⇌ NH4+ + OH-1
When an acid (nitric acid) and an alkali or base combine completely to form salt and water then the reaction is called a neutralization reaction.
NH4OH + HNO3 ⟶ NH4NO3 + H2O
Hence, the reaction between liquor ammonia and nitric acid is a neutralization reaction.
