For the reaction Co + Cl₂ → CoCl₂ ,which statement is TRUE? A)The cobalt is oxidized because its oxidation state changed from 0 to +2. B)The cobalt is oxidized because it gained two electrons. C)The oxidation state of each chlorine atom in Cl₂ is -1. D)Each chlorine atom is oxidized. E)none of the above

Question

Quizplus · Accepted Answer

The reaction involves the oxidation of cobalt, as its oxidation state changes from 0 to +2. This is because it loses two electrons to form the CoCl₂ compound. Chlorine, on the other hand, undergoes reduction as it gains electrons in the process. The oxidation state of each chlorine atom in Cl₂ is -1, but this is not relevant to the question asked. Therefore, option A is the correct answer.
