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
