Show transcript
Ammonia can be synthesised in the lab by heating a mixture of NH₄Cl and NaOH, producing NH₃ gas and other by-products.
Ammonia is an alkaline gas that reacts readily with water to form a corrosive, basic solution.
Ammonia gas turns moist red litmus paper blue, indicating its alkaline nature.
Ammonia gas is soluble, toxic, and has a pungent smell, requiring careful handling.
Ammonia reacts with hydrogen chloride (from concentrated hydrochloric acid) to form white fumes of ammonium chloride.
