Using these standard reduction potentials, identify the strongest reducing agent: E°(Cr₂O₇²⁻/Cr³⁺) = +1.33 V; E°(Cl₂/Cl⁻) = +1.36 V; E°(MnO₄⁻/Mn²⁺) = +1.51 V; E°(Cr³⁺/Cr) = −0.74 V.
Options:
Answer:
B
Solution:
Chromium metal has the most negative listed reduction potential (Cr³⁺/Cr), so it is most readily oxidised.
