Copper can be extracted by hydrometallurgy but not zinc. Explain.

Options

A. Copper is comparatively less active metal as its reduction potential is high. It can be displaced from solutions of `Cu^(2+)` ion by more active metals
B. `Zn` displaced from solution of `Zn^(2+)` ion, a more reactive metal than it, but then readily reacts with water forming their corresponding ions and evolve hydrogen gas
C. Both (a) and (b) are correct
D. Copper can never be extracted by hydrometallurgy

Answer

B
