1.	Consult the table of the standard electrode potentials and suggest three substances that can oxidize ferrous ions under suitable conditions.
Answer» For the oxidation of ferrous ion, following reaction will take place Fe²⁺ → Fe³⁺ + e^– E°_ox = – 0.77 V Only those substances can oxidise ferrous ion into ferric ion, which are stronger oxidising agents and have positive reduction potentials greater than 0.77 V so that EMF of the cell reeaction is positive. This is so for elements lying below Fe³⁺/Fe²⁺ in the electrochemical series e.g Br₂, Cl₂, and F₂.
