Electron flow Voltmeter Porous barrier or salt bridge Anode Cathode (-) (+) - Anions Cations - Anode half-cell, Cathode half-cell, oxidation occurs reduction occurs
A voltaic cell similar to that shown in Figure is constructed.
One electrode half-cell 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) + 2 Ag+(aq)---->Fe2+(aq) + 2 Ag(s)
(a) What is being oxidized, and what is being reduced?
(b) Write the half-reactions that occur in the two half-cells.
(c) Which electrode is the anode, and which is the cathode?
(d) Indicate the signs of the electrodes. (e) Do electrons
flow from the silver electrode to the iron electrode or from
the iron to the silver? (f) In which directions do the cations
and anions migrate through the solution?
