Question
Consult the table of standard electrode potentials and suggest three substance that can oxidize ferrous ions under suitable conditions.
Solution
Answer:
oxidation of ferrous ion means :
Fe2+--> Fe3+ +e- ;
Any substance which standard electrode potential is more than that of Fe+3 /F+2 can oxidise ferrous ions.
(refer to the table given in book)
The EMF of the substance whose reduction potentials greater than 0.77V will oxidised ferrous ion.
for example Br2, Cl2,and F2 .
