Oxides, Hydroxides and Ammonia Flashcards
What are oxides and metal oxides examples of?
Bases
Soluble oxides and metal hydroxides are known as?
Alkalis, because they dissolve in water.
All metal oxides and metal hydroxides react with acids to form a ____ and _____.
Salt and water. These are neutralisation reactions.
The combination of metal and acid decides the ____.
Salt.
Example!
Hydrochloric Acid + Copper Oxide —-> Copper Chloride + Water
Ammonia can be neutralised with _____ to make fertiliser.
HNO3 (nitric acid).
Ammonia dissolves in water to make an _______ ______.
An alkaline solution.
When ammonia reacts with nitric acid, you get a neutral ____ called _______ nitrate.
A neutral salt called Ammonium Nitrate.
How’s the reaction between ammonia and nitric acid different to a normal neutralisation reaction?
No water is produced
Why’s ammonium nitrate particularly good as a fertiliser?
Because it contains 2 sources of nitrogen. There’s nitrogen in the ammonia and in the nitric acid. Plants requires nitrogen to make proteins.
