Electrochemistry

There are two types of electrochemical cells which you should be familiar with:

1. Electrolytic cells
2. Galvanic or voltaic cells

What type of chemical reaction takes place in both types of electrochemical cells?

A re-dox reaction. You can review this in the red-ox chapter on page .

What charges are found at the cathode and anode?

The ca+hode is where positive charges are concentrated and the anode is where negative charges are concentrated.

What red-ox half reaction occurs at the anode and the cathode?

Oxidation occurs at the anode.
Reduction occurs at the cathode.

What are reduction potentials and cell potentials?

A reduction potential is the energy required to force an atom or molecule to release an electron.

Cell potential is the difference in potential between the two electrodes of a cell.

Both are measured in volts.
