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
