Answer:
Option (A) Each Zn atom loses 2 electrons, and each Co2+ ion gains 2
Explanation:
To know the right answer to the question, let us observe the changes in the oxidation number of Zn and Co. This is illustrated below:
Zn(s) + Co2+(aq) → Zn2+(aq) + Co(s)
The oxidation number of Zn changes from 0 to +2 indicating that Zn has lose 2 electrons.
The oxidation number of Co changes from +2 to 0 indicating that Co has gain 2 electrons.
Therefore, option A is the correct answer.
