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

Q3.3: Consult the table of standard electrode potentials and suggest three substances that an oxidise ferrous ions under suitable conditions.

Solution:

Any substance which standard electrode potential is more than that of Fe⁺³ /F⁺² can oxidise ferrous ions.

standard electrode potential table

All the elements (like F₂,Cl₂  and O₂) of the table can oxidized ferrous ions
