Method: Dip a glass rod in concentrated hydrochloric acid and put this in a sample of the gas. Result: If ammonia is present, a white ‘smoke’ of ammonium chloride is observed.

A cotton swab is dipped into concentrated hydrochloric acid (producing hydrogen chloride gas) while a second on is dipped into concentrated aqueous ammonia (producing ammonia gas). Both cotton swabs ...

Ammonia is made from nitrogen and hydrogen, with the hydrogen typically derived from natural gas. "Natural gas contains both carbon and hydrogen, but you only need the hydrogen for ammonia.

A cleaner alternative In preparation for designing ... more efficiently than hydrogen gas due to its higher energy density. The innovation positions ammonia as a linchpin in decarbonizing ...
