Identify the use of electrolysis as a means of cleaning and stabilising iron, copper and lead artefacts

  • Electrolysis can be used to stabilise the structure of metal artefacts by removing salt.
  • Concretions of calcium carbonate can be loosened from the surface of artefacts by hydrogen gas produced through electrolysis.
