Resource summary
Oxides, Hydroxides and Ammonia
Metal Oxides and Metal Hydroxides Are Bases!
Some metal oxides and hydroxides dissolve in water/ These are alkalis
Even bases that won't dissolve in water will react with acids
All metal oxides and metal hydroxides react with ACIDS to form a salt and a water
Acid + Metal Oxide --> Salt + Water
Acid + Metal Hydroxide --> Salt + Water
NEUTRALISATION REACTIONS!
Combination of Metal anf Acid decides the Salt!
Hydrochorid acid + copper oxide = copper chloride + water
Hydrochloric acid + sodium hydorxide = sodium chloride + water
Sulphuric acid + zinc oxide = zinc sulfate + water
Sulfuric acid + calcium hydroxide = calcium sulfate + water
H2SO4 + ZnO --> ZnSO4 + H20
hn03 + koh --> kno3 + h20
Ammonia can be NEUTRALISED w/HNO2 to make fertiliser
Ammonia dissolves in h20 to make an alkaline solution
When it reacts with nitric acid, you get a neutral salt - ammonium nitrate
NH3 + HNO3 --> NH4NO3
AMMONIA + NITRIC ACID --> aMMONIUM NITRATE
Doesn't produce water -unusal!
Good fertiliser because it has nitrogen from two sources, the ammonia and the nitric acid - double dose!
Plants need nitrogen to make proteins
