Exhibit 18-2 Consider a voltaic cell that is constructed from a strip of Ag dipped in an AgNO₃ solution and a Fe (s) strip dipped in a solution of FeCl₂ to answer the following question(s) . An external circuit and a salt bridge connect these two electrodes.
-Refer to Exhibit 18-2. Which electrode is the negative electrode and what is the standard potential E ° _cell for this voltaic cell?

Question

Quizplus · Accepted Answer

The Fe/Fe^2+ couple has a lower standard reduction potential than the Ag/Ag^+ couple, making the Fe electrode the anode (negative electrode) in this voltaic cell. The standard cell potential (E°_cell) is calculated by subtracting the anode potential from the cathode potential, resulting in a positive value of 1.24 V.
