Question

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

Solution

Substances that are stronger oxidising agents than ferrous ions can oxidise ferrous ions.

`Fe^(2+) -> Fe^(3+) +e^(-1); E^(theta) = -0.77 V`

This implies that the substances having higher reduction potentials than 
+0.77 V can oxidise ferrous ions to ferric ions. Three substances that can do so are F2, Cl2, and O2.

  Is there an error in this question or solution?
