What is the reduction half-reaction for the following overall galvanic cell reaction? Pb²⁺(aq)+ 2 Ag(s)→ Pb(s)+ 2 Ag⁺(aq)

Quizplus · Accepted Answer

The reduction half-reaction is the half-reaction that involves the gain of electrons. In the given overall galvanic cell reaction, Pb is being reduced, which means it is gaining electrons. Therefore, the reduction half-reaction would involve Pb, and the correct choice is C, which shows the reduction of Pb²⁺(aq) to Pb(s). The other choices involve the oxidation half-reaction or the reduction of Ag, which is not the reaction that is occurring at the cathode in this cell.
