Oxides, Hydroxides and Ammonia
Metal Oxides and Metal Hydroxides are Bases.
- Some metal oxides and metal hydroxides dissolve in water. These soluble compounds are called Alkalis
- So all metal oxides and metal hydroxides will react with acids to form a salt and water:
Acid + Metal Oxide = Salt + Water
Acid + Metal Hydroxide = Salt + Water
Oxides, Hydroxides and Ammonia 2
The combination of Metal and Acid decides the salt:
Hydrochloric acid + copper oxide = copper sulfate + water Hydrochloric acid + sodium hydroxide = sodium chloride + water
Sulfuric acid + zinc oxide = zinc sulfate + water Sulfuric acid + calcium hydroxide = calcium sulfate + water
Nitric acid + magnesium oxide = magnesium nitrate + water Nitric acid + potassium hydroxide = potassium nitrate + water
Oxides, Hydroxides and Ammonia 3
Ammonia can be neutralised with HN03 to make fertiliser.
Ammonia dissolves in water to make an Alkaline Solution. When it reacts with Nitric Acid, you get a neutral salt - Ammonium nitrate
NH3(aq) + HNO3(aq) = NH4NO3(aq)
Ammonia + Nitric acid = Ammonium nitrate
There is No water produced!
