Iron oxidation in concentrated chloride media

WebMay 23, 2024 · During iron oxidation, ferrous bicarbonate Fe (HCO3)2 is oxidized to form ferric hydroxide Fe (OH)3. Both iron and manganese oxidation are heavily dependent on pH. Below a pH of 7, oxidation processes are very slow and require a long contact time for oxidation to occur. WebSep 16, 2024 · This must be balanced by the positive charge on three iron atoms, giving an oxidation state of +8/3 for iron: [ (4 O atoms) (−2)]+ [ (3 Fe atoms) ( + 8 3) ]= 0 Fractional oxidation states are allowed because oxidation states are a somewhat arbitrary way of keeping track of electrons.
