Question

Which of the statements listed below is true regarding the following redox reaction occurring in a nonspontaneous electrochemical cell? Cd(s)+ Zn(NO₃)2(aq)  Zn(s)+ Cd(NO₃)2(aq)

Quizplus · Accepted Answer

In a nonspontaneous reaction, electrons are forced to flow from the cathode to the anode due to an external electrical source. Therefore, the metal ions will be reduced (gain electrons) at the cathode and form a solid metal while the metal will be oxidized (lose electrons) at the anode and dissolve into ions. In this case, Zn(NO₃)2 is the cathode and Cd is the anode. So, Zn metal will be produced at the cathode (D) and Cd will dissolve into ions at the anode. The oxidation half-reaction is Cd → Cd₂+ + 2 e- (B) and the reduction half-reaction is Zn²⁺ + 2 e- → Zn (A).
