In the redox reaction2Fe2++CI2→2Fe3++2Cl−
Cl2 is reduced because it has lost electrons
Cl2 is reduced because its oxidation number has decreased
Cl2 is reduced because its molecule is change to two ions
Fe2+ is reduced because it has lost electrons
Fe2+ is reduced because it has gained electrons
Correct answer is B
decrease in oxidation number indicates reduction while an increase in oxidation number indicates oxidation hence chloride gas is reduced because its oxidation number changed from o to -1
