Question

A electrolytic cell similar to that shown in the figure above is constructed. The electronic device shown at the top of the figure is a power supply. One electrode compartment consists of a silver strip placed in a 1.0 M AgNO3 solution, and the other has a cadmium strip placed in a 1.0 M CdCl2 solution. The overall cell reaction is:

Figure out which electrode is the anode, which is the cathode, the signs on these electrodes, the direction in which the electrons flow through the power supply, and the direction in which cations and anions migrate through the salt bridge and solutions. Use this work to pick the statement from below which is false.

a) Electrons flow from the cadmium electrode to the silver electrode through the power supply.
b) The silver electrode is the anode and the cadmium electrode is the cathode.
c) The silver electrode is positive and the cadmium electrode is negative.
d) Cations migrate from the salt bridge to the 1.0 M CdCl2 solution.
e) Anions migrate from the salt bridge to the 1.0 M AgNO3 solution.

Explanation / Answer

Anode: Silver

Cathode: cadmium

In an electrolytic cell, the anode is taken to be positive while the cathode is negative (cadmium)

The electrons from the anode flow to the positive terminal of the battery, and electrons from the battery flow to the cathode (cadmium)

So False statement is

a) Electrons flow from the cadmium electrode to the silver electrode through the power supply.
