What happens when hydrogen halides react with ammonia gas?
Ammonium salts are formed.
In the context of the text, what is an example of a disproportionation reaction involving chlorine?
Chlorine reacting with hot alkali
Explore the reactivity of chlorine when reacted with hot, concentrated alkali and its disproportionation to form different species with specific oxidation numbers. Learn about how Group 1 and Group 2 metals react with chlorine gas, resulting in the formation of metal chlorides through oxidation-reduction reactions.
