Consider the case where the Cu2+/Cu and Zn2+/Zn half cells are connected in an electrochemical cell, as shown below. In the picture, the two black rectangles are the metal electrodes, connected by an external wire. The electrodes are immersed in solutions of their respective ions. Use the table of Standard Reduction Potentials in the Lab Manual to answer the following questions. (a) Which direction do the electrons go in the external wire? toward the zinc electrode toward the copper electrode (b) In which half cell will a reduction take place? Zn2+/Zn Cu2+/Cu (c) Which half cell is the anode? Cu2+/Cu Zn2+/Zn (d) Which direction do the anions in the salt bridge flow? toward the zinc cell toward the copper cell (e) Select the true statement about phenomena at the electrodes. The copper electrode increases in mass, and the zinc electrode decreases in mass. The zinc electrode increases in mass, and the copper electrode decreases in mass. (f) What happens if the leads to the copper and zinc electrodes are switched? The electrodes switch function, so the zinc is reduced and the copper is oxidized, and the sign of the voltage reading changes. The direction of current flow through the meter is reversed, and the sign of the voltage reading changes. (g) What is the standard cell potential (E°cell)?
