Which of the following reactions will require the use of an inert electrode when used in a voltaic cell? A) Co(s)+ 2 Ag⁺(aq)→ 2 Ag(s)+ Co²⁺(aq) B) 3 Ni(s)+ 2 Au³⁺(aq)→ 3 Ni²⁺ + 2 Au(s) C) Cu(s)+ 2 Ag⁺(aq)→ Cu²⁺(aq)+ 2 Ag(s) D) Zn(s)+ 2 MnO₂(s)+ 2 NH₄⁺(aq)→ Zn²⁺(aq)+ Mn₂O₃(s)+ 2 NH₃(aq)+ H₂O(l) E) 3 Zn²⁺(aq)+ 2 Al(s)→ 3 Zn(s)+ 2 Al³⁺(aq)

Question

Quizplus · Accepted Answer

Inert electrodes are required when the reactants or products do not include a solid metal that can serve as an electrode. In option D, the reaction involves MnO2 and NH4+, which do not provide a solid metal electrode, necessitating the use of an inert electrode for the voltaic cell to function.
