Key Concepts

Electrolysis

• Electrolysis involves using an electric current to drive a non-spontaneous chemical reaction.
• It is used extensively in industry, especially for the separation of elements from their naturally occurring sources.

Molten Ionic Compounds

• Ionic compounds are substances formed by the chemical bonding of ions of opposite charges.
• In molten form, these compounds become conductive, allowing them to undergo electrolysis.

Process of Electrolysis

• Electrolysis of molten ionic compounds involves the movement of ions towards electrodes of opposite charge.
  • Anode: Positively charged electrode where oxidation occurs.
  • Cathode: Negatively charged electrode where reduction occurs.
• The ions gain or lose electrons, resulting in the formation of elements.

Applications

• Industrial Use: Electrolysis is crucial in industries for extracting metals, such as aluminum, from their ores.
• Electroplating: Used in coating objects with a layer of metal for protection or aesthetic purposes.
