Using the data given in Q.8 find out in which option the order of reducing power is correct.

(i) Cr^{3+} < Cl^{-} < Mn^{2+} < Cr

(ii) Mn^{2+} < Cl^{-}< Cr^{+3} < Cr

(iii) Cr^{3+} < Cl^{-}< Cr_{2}O_{7}^{2-} < MnO^{-}_{4}

(iv) Mn^{2+} < Cr^{3+} < Cl^{-}< Cr

Answers (1)

The answer is the option (ii). A decrease in reduction potential corresponds with an increase in reduction power. The order of reducing power is (ii) Mn^{2+} < Cl^{-}< Cr^{+3} < Cr
