What is the reduction half-reaction for the following overall galvanic cell reaction? Zn²⁺(aq)+ 2 Ag(s)→ Zn(s)+ 2 Ag⁺(aq) A)Ag(s)+ e^- → Ag⁺(aq) B)Ag⁺(aq)+ e^- → Ag(s) C)Zn²⁺(aq)+ 2 e^- → Zn(s) D)Zn²⁺(aq)+ e^- → Zn(s)

Question

Quizplus · Accepted Answer

The reduction half-reaction corresponds to the half-reaction where reduction of a species occurs. In the given reaction, Zn is being reduced to Zn2+ ions, therefore the reduction half-reaction will have Zn on the product side. The other reactant, ²(aq), does not get reduced or oxidized in the given reaction, hence it will not be included in the reduction half-reaction. The reduction half-reaction for the given reaction is: Zn^{2 +}(aq) + 2 e- → Zn(s) Option A is incorrect because it represents the oxidation half-reaction for the reduction half-reaction shown in option B. Option B is incorrect because it represents the oxidation half-reaction for silver ions being reduced to Ag atoms. Option D is incorrect because it represents the reduction half-reaction for the oxidation half-reaction shown in option A.
