    • what does Fe2+ ions react with in I- and S2O8 2- reaction and what is produced?
      Reacts with : S2O8 2-
      products : 2SO4 2- and 2Fe3+
    • what does Fe3+(aq) ions react with in I-(aq) and S2O8 2-(aq) reaction and what is produced (make sure its balanced) ?
      reacts with : 2I-(aq)
      produces : 2Fe2+(aq) and I2(aq)
    • what features of iron makes it a good catalyst in the catalysis of I- and S2O8 2- to form SO4 2- and I2
      variable oxidation states
      positive charge (both reactants are negative so normally they would repel each other)
    • what is I- oxidised by to form I2
      Fe3+
