TUTOR Identify the Components of a Voltaic Cell
A voltaic electrochemical cell is constructed using the following reaction. The half-cell components are separated by a salt bridge.
Hg2+ (aq) + Cd(s)→→→→→→ Hg(1) + Cd²+ (aq)
Write the reactions that take place at the anode and at the cathode, the direction in which the electrons migrate in the external circuit, and the
direction the anions in the salt bridge migrate.
Use smallest possible integer coefficients.
If a box is not needed, leave it blank.
Enter the reaction that takes place at the anode. Include state symbols:
+
+
Enter the reaction that takes place at the cathode. Include state symbols:
