Given these standard reduction potentials: E°(Cr₂O₇²⁻/Cr³⁺) = +1.33 V; E°(Cl₂/Cl⁻) = +1.36 V; E°(MnO₄⁻/Mn²⁺) = +1.51 V; E°(Cr³⁺/Cr) = −0.74 V. Which order of reducing power is correct?

Options:

Answer:
B
Solution:

Reducing strength rises as the standard reduction potential of its conjugate couple falls: Mn²⁺ < Cl⁻ < Cr³⁺ < Cr.
