Study Notes
Electrodes and Electrolytes
- An electrode is a conductor of electricity that can carry electric current into non-metals and other poor conductors of electricity.
- A solution that breaks into its ions on passing electricity through it is called an electrolyte.
- Electrolytes are used in the process of electroplating.
Types of Electrodes
- The positively charged electrode is called an anode.
- The negatively charged electrode is called a cathode.
Ions
- An anion is a negatively charged ion.
- A cation is a positively charged ion.
Test your knowledge on electrodes, electrolytes, anodes, cathodes, anions, and cations. Learn about their roles in conducting electricity and the process of electroplating.
