Sulfur and Sulfuric acid
  1. Sulfur
    1. Sources
      1. Mining
        1. sulphide ores
          1. Natural gas and petroleum
          2. Uses
            1. manufacturing sulfuric acid
              1. make rubber tyres flexible (vulcanising)
                1. making dyes
              2. Sulfur dioxide
                1. sources
                  1. volcanoes
                  2. uses
                    1. used as bleach during manufacture of paper from wood pulp
                      1. bleaching silk as well
                      2. preserve food and drinks
                        1. kills present bacteria
                          1. sulfite ions usually added
                            1. SO3 (2-) + 2H (+) -------> SO2 + H20
                        2. It is the gas given off when sulfur burns
                          1. S + O2 -----> SO2
                          2. also made from roasting ores
                            1. 2ZnS + 3O2 ----> 2ZnO + 2SO2
                          3. Sulfuric acid
                            1. is a dibasic acid.
                              1. It has 2 hydrogen ions per molecule that can react
                                1. H2SO4 + 2NaOH ----> NaSO4 + H20
                                  1. sulfuric acid + sodium hydroxide -----> sodium sulfate + water
                              2. H2SO4
                                1. it is a strong acid with typical acid properties
                                  1. reacts with metals above hydrogen in reactivity series to form a salt and hydrogen
                                    1. H2SO4 + Zn ----> ZnSO4 + H2
                                    2. reacts with metal oxide to form salt and water
                                      1. H2SO4 + MgO ---> MgSO4 + H20
                                      2. reacts with metal hydrixide to form salt and water
                                        1. H2SO4 + 2KOH ----> K2SO4 + 2H2O
                                        2. reacts with metal carbonate to form salt, water and carbon dioxide
                                          1. H2SO4 + Na2CO3 ---> Na2SO4 + H20 + CO2
                                          2. can form hydrogensulfates by replacement of one of hydrogen ions
                                            1. H2SO4 + NaOH ---> NaHSO + H20
