Galvanic cells pt 3/3

An electrode is the conductor of a cell which is connected to the external circuit.
An electrolyte is a substance which in solution or molten conducts electricity.

The electrode in which oxidation occurs is the anode [the negative terminal].
The electrode in which reduction occurs is the cathode [the positive terminal].

To maintain electrical neutrality with the flow of electrons overhead from the cathode to the anode, anions/cations (-ve/+ve ions) in solution migrate to the anode/cathode from the cathode/anode through the connecting salt bridge.
