6. Electrolysis
Electrolysis involves the chemical decomposition of electrolytes through electric current, converting electrical energy into chemical change. Key concepts include types of substances based on conductivity, the process of electrolysis of various solutions, and the importance of Faraday's laws. Applications span from electroplating to the purification of metals.

What we have learnt
- Electrolysis is the process of using an electrical current to drive a chemical reaction.
- Electrolytes can be strong or weak based on their ability to conduct electricity.
- Faraday's laws relate the amount of substance produced during electrolysis to the electric current used.
Key Concepts
- -- Electrolyte
- A substance that conducts electricity in molten or aqueous solution and breaks down chemically.
- -- Electrodes
- Conductors through which current enters and leaves the electrolyte, consisting of an anode (positive) and a cathode (negative).
- -- Cations and Anions
- Cations are positively charged ions that move towards the cathode, while anions are negatively charged ions that move towards the anode.
- -- Faraday's Laws
- These laws describe the relationship between electric charge and the amount of substance transformed during electrolysis.
- -- Electroplating
- Coating objects with a thin layer of metal to enhance appearance and prevent corrosion.
