In the following electrochemical cell,what is the role of the platinum?
Cu(s) | Cu²⁺(aq) || Fe³⁺(aq) ,Fe²⁺(aq) | Pt(s)

Question

In the following electrochemical cell,what is the role of the platinum? Cu(s)| Cu²⁺(aq)|| Fe³⁺(aq),Fe²⁺(aq)| Pt(s)

Quizplus · Accepted Answer

The platinum serves as a catalytic surface where the reduction of Fe³⁺ takes place, as it facilitates the transfer of electrons between the Fe³⁺ ions and the electrode. The oxidation of Fe²⁺ occurs at the electrode made of iron. The copper electrode served as a reference electrode. Therefore, the correct choice is C, as platinum reduces Fe³⁺.
