Question

A voltaic cell SIMILAR to that shown in Figure 20.5 is constructed. One electrode compartment consists of a silver strip placed in a solution of AgNO3, and the other has a iron strip placed in a solution of FeNO3, The overall cell reaction is given below.
(Ered Fe+2 is -0.440)

(a) Write the half-reactions that occur in the two electrode compartments. (Type your answer using the format [Ag]+ for Ag+ and Ag for Ag. Also, the first box gets the coefficient)

(Ered Fe+2 is -0.440) 2 Ag+(aq) + Fe(s) 2 Ag(s) + Fe2+(aq) (a) Write the half-reactions that occur in the two electrode compartments. (Type your answer using the format [Ag]+ for Ag+ and Ag for Ag. Also, the first box gets the coefficient)

Explanation / Answer

Half cell (Reduction)

2[Ag+(aq)] + 2 e- --> 2Ag(s)

Half cell ( Oxidation)

Fe(s) --> [Fe2+(aq)] + 2e-
