What is electrolysis?

Electrolysis is the process of decomposition of a substance known as an electrolyte when a direct electric current is passed through it.

An electrolyte is a substance that conducts electricity in the molten or aqueous state and which is decomposed during the process.

The element discharged during an electrolytic process depends on:

  • the position of the element in the electrochemical series
  • the concentration of the ion of the element
  • the nature of the electrode

An aqueous salt of sodium will always produce hydrogen gas and oxygen gas at the electrodes.
