13

Cations:________

positively charged ions

14

If a pair of large electrical contacts, or electrodes, connected to a power source are dipped into an electrolyte solution, POSITIVELY CHARGED IONS (_____) in the solution will be attracted to the electrode called the CATHODE and negatively charged ions ANIONS) in the solution will be ATTRACTED toward the electrode called the ANODE. This movement of ions allows the solution to conduct an electric current between the wires. The flow of charge in the solution is due to the movement of ions.
