Mg2+(aq) + 2e->(aq) → Mg(s)E°(volts) = 2.370 Zn2+(aq) + 2e->(aq) → Zn(s)E°(volts) = -0.763 Cds2+(aq)...

JAMB 1998

Mg²⁺_(aq) + 2e^->_(aq) → Mg_(s)E°_(volts) = 2.370

Zn²⁺_(aq) + 2e^->_(aq) → Zn_(s)E°_(volts) = -0.763

Cds²⁺_(aq) + 2e^->_(aq) → Cd_(s)E°_(volts) = 0.403

Cu²⁺_(aq) + 2e^->_(aq) → Cu_(s)E°_(volts) = 0.340

In the electrochemical series above, the strongest reducing agents is?

A. Cu _(s)
B. Cd_(s)
C. Znsub>(s)
D. Mg_(s)
