Zusammenfassung der Ressource

The manufacturing of halogens
  1. manufacturing of iodine
    1. can be obtain either by sea weed of electrolysis of brine like the others
    2. manufacturing of chlorine
      1. electrolysis
        1. the reactant are NaCl and H2O
          1. reactants are NaOH and H and Cl
            1. methods
              1. mercury cell
                1. diaphragm cell
                2. membrane cell
            2. manufacturing of fluorine
              1. electrolysis
                1. reactants are CaF2 and H2SO4
                  1. products are CaSO4 and 2HF
                    1. this is further electrolysed to form F and H
                2. manufacturing of bromine
                  1. can be extracted from the dead sea
                    1. this is done by using a more reactive halogen like chlorine for electrolysis
                      1. It also further can be extracted from the brine from an industrial extracting mechanisms
