Resource summary

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