Question

1. If you made a new voltaic cell with Zn and Ag electrodes, what metal would be the anode and which would be the cathode?
2. In this new cell, what electrode would be oxidized and which will be reduced?
3. In this new cell, what direction would electrons flow?
4. Write the half reaction that occurs at the anode and cathode.

Answer 1

Answer:

Explanation:

1. If you made a new voltaic cell with Zn and Ag electrodes, what metal would be the anode and which would be the cathode?

Zn loses its electron so it is anode. Ag is the cathode.

2. In this new cell, what electrode would be oxidized and which will be reduced?

Oxidation happens at anode which is Zn. Reduction happens at cathode which is Ag.

3. In this new cell, what direction would electrons flow?

Zn -> Ag

4. Write the half reaction that occurs at the anode and cathode.

Zn -> Zn++ + 2e-

2Ag+ + 2e- -> 2Ag
