MetalsElectrolysis

We use metals in everyday life, for example in jewellery or cars. They have many uses due to their properties which include strength, malleability, conduction of electricity and conduction of heat.

Electrolysis

Another example of a redox reaction is the electrolysis of an ionic compound. During electrolysis:

  • negative ions lose electrons at the positive electrode (oxidation)
  • positive ions gain electrons at the negative electrode (reduction)

Watch this video to see a demonstration of electrolysis of copper chloride solution.
