The diagram below represents a voltaic cell. In this cell, which species is reduced? Zn(s)|Zn²⁺(1.0 M)||Cu²⁺(1.0 M)|Cu(s)

Question

Quizplus · Accepted Answer

In a voltaic cell, the species that is reduced is the one that gains electrons at the cathode. In this cell, the cathode has Cu(s), which means that Cu is being reduced (since it goes from a cation, Cu2+, to Cu). Therefore, the correct choice is (C), which has Cu2+ ions in solution that are being reduced to form Cu(s).
