The standard oxidation potential of Zn and Ag at C are

Which of the following reactions actually takes place?

(A)\mathrm{Zn_{(s)} + 2Ag^+_{(aq)} \rightarrow Zn^{2+}_{(aq)} + 2Ag_{(s)}}Correct
(B)\mathrm{Zn^{2+}_{(aq)} + 2Ag_{(s)} \rightarrow 2Ag^+_{(aq)} + Zn_{(s)}}
(C)\mathrm{Zn_{(s)} + Ag_{(s)} \rightarrow Zn^{2+}_{(aq)} + Ag^+_{(aq)}}
(D)\mathrm{Zn^{2+}_{(aq)} + Ag^+_{(aq)} \rightarrow Zn_{(s)} + Ag_{(s)}}

Answer: (A)

Solution

Zn has the higher oxidation potential, so it is oxidised and is reduced, with V for $\mathrm{Zn +
