Question

Copper ($Cu$) is uniquely the only metal in the 3d transition series that has a positive standard reduction potential ($E^\circ = +0.34	ext{ V}$). Consequently, which characteristic behavior does it exhibit?

Prashant Kotian · Accepted Answer

Correct answer: B. A positive value means the metal is resistant to oxidation and is a poor reducing agent. Because its high sublimation and ionization energies are not compensated by hydration energy, Copper cannot reduce to gas.
