Copper is displaced from the solution of its salts by most metals because it A. is a transition element B. has completely filled 3d-orbitals C. is at the bottom of the activity series D. is very reactive
- A. is a transition element
- B. has completely filled 3d-orbitals
- C. is at the bottom of the activity seriesCorrect
- D. is very reactive
Explanation
Copper is commonly displaced from its solutions by most metals because it is almost at the bottom of the electrochemical (activity) series. Only mercury, silver, gold and platinum are less reactive than copper.
