If two metallic ions of the same concentration migrate to a graphite cathode, the one that would be preferentially discharged is that with the
- greater stability in solution
- lower electrical charge
- smaller mass
-
stronger tendency to accept electrons
- stronger tendency to lose electrons.
The correct answer is: D
Explanation
In an electrolytic cell, when two metallic ions of the same concentration migrate to a graphite cathode, the one that would be preferentially discharged is the one that has the stronger tendency to accept electrons and become a neutral atom.
