For the galvanic cell Pt(s)∣ Sn²⁺(aq),Sn⁴⁺(aq)∣∣ Pb²⁺(aq)∣ Pb(s),what is the function of the Pt(s)?

Question

Quizplus · Accepted Answer

The function of Pt(s) in the galvanic cell is to serve as the electrode at which the oxidation reaction takes place. In this case, the oxidation reaction takes place at the Sn²⁺(aq)/Pt(s) interface, resulting in the release of electrons that flow through the external circuit to the Pb(s)/Pb²⁺(aq) interface, where reduction takes place. Since Pt(s) is not involved in the overall cell reaction, it does not appear in the balanced equation for the cell. Therefore, choice B is the correct answer.
