Consult the table on standard electrode potentials and suggest three substance that can oxidise ferrous ions under suitable conditions. |

Answer» `Fe^(2+)` (ferrous) ions gets oxidised to `Fe^(3+)` (farriec) ion as follows `Fe^(2+) to Fe^(3+)+e^(-)E_(0x)^(0)=-0.77V` Only those substances can oxidise `Fe^(2+)` ions to `Fe^(3+)` ions which can accept electrons released during oxidation or are placed above iron in electrochemical series. Three such substances are `Cl_(2)(g), Br_(2)(g) and F_(2)(g).` |
