Oxides, Hydroxides, ammonia
- Metal oxides and hydroxides are bases
- Some dissolve is water and therefore are alkalis
- But they still can react with acids even if they don’t dissolve in water
- Acid + metal oxide = salt + water
- Acid + metal hydroxide = salt + water
Ammonia
- Ammonia can be neutralised with HNO3 (nitric acid) to make fertiliser
- Ammonia + nitric acid = ammonium nitrate
- This is different from most other reaction because it only produces a salt
- NH3 + HNO3 = NH4NO3
- This is really good for plants because it has two forms of nitrogen which plants use to make protein
