What is oxidation?

Back

It is the loss of electrons.

Front

What is a galvanic cell?

Back

A device that converts chemical energy into electrical energy through spontaneous redox reactions.

Front

What is cell potential?

Back

The measure of the voltage or electromotive force of a galvanic cell.

Front

What is the role of the salt bridge in a galvanic cell?

Back

It maintains electrical neutrality by allowing the flow of ions between the two half-cells.

Front

What happens at the anode of a galvanic cell?

Back

Oxidation occurs, releasing electrons.
