In the redox reaction\( 2Fe^{2+} + CI_2 → 2Fe^{3+} + 2Cl^-\)
- 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
The correct answer is: B
Explanation
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
