Question -

Consult the table of standardelectrode potentials and suggest three substances that can oxidise ferrous ions under suitable conditions.



Answer -

Substancesthat are stronger oxidising agents than ferrous ions can oxidise ferrous ions.

This implies┬аthat the substances having higherreduction potentials than
+0.77 V can oxidise ferrous ions to ferric ions. Three substances that can doso are F2,Cl2,and O2.
