Solution: A voltaic cell similar to that shown in Figure 20.5 in the textbook is constructed. One electrode compartment consists of a silver strip placed in a solution of AgNO3, and the other has an iron strip

Problem
A voltaic cell similar to that shown in Figure 20.5 in the textbook is constructed. One electrode compartment consists of a silver strip placed in a solution of AgNO3, and the other has an iron strip placed in a solution of FeCl2. The overall cell reaction is
Fe(s) + 2Ag+(aq)  →  Fe2+(aq) + 2Ag(s)


Which electrode is the anode, and which is the cathode? What are the signs of the electrodes? Do electrons flow from the silver electrode to the iron electrode, or from the iron to the silver? In which directions do the cations and anions migrate through the solution?
