Consult the table of standard electrode potentials and suggets three substances that can oxidise ferrous ions under suitable conditions.

Answer»

Solution :* Substances that are stronger OXIDISING agents than ferrous ions can oxidise ferrous ions.
`Fe^(2+) to Fe^(3+) +e^(-)(E_(Fe^(2+)|Fe)^(THETA)=0.77V)`
* This implies that the substances having HIGHER reduction POTENTIAL than +0.77 V can oxidise ferrous ions to ferric ions. Three substances that can do so are `F_(2), Cl_(2) and O_(2)`.
