This catalyst is brown in colour and not easily poisoned. It is used in combination with other compounds.
Ammonia does not settle in low - lying areas.
When this gas dissolved in water, a hydroxide is formed, which is basic in nature and turns red litmus blue.
The reaction of nitric acid with protein keratin present in the skin is called xanthoproteic reaction.
Recall the gas produced
Remember the uses of ammonia.
N2 + 3H2→2NH3
The protonation of water rapidly takes place and forms hydronium ions.
When ammonia gas is burned in oxygen, the products formed are water and nitrogen monoxide gas.
Mg3N2 + 6H2O→3 Mg(OH)2 + 2NH3
