- Solution of ammonia in water contains hydroxyl ions.
- Thus it has many properties of a typical alkali.
- Ammonia salts are similar to metallic salts.
- The group precipitates in the reaction as a whole without splitting in any way.
- It exhibits unit valency in its compounds and therefore called a basic radical.
Note:
- It cannot exist freely as ammonia gas which is a compound.
- Like other alkalis, ammonia solution precipitates insoluble metallic hydroxides by double decomposition when mixed with solution of salts of the metals.
