How to make copper sulphate

This is an easy way to produce copper sulphate either at home, at school or in a laboratory.

Please note: As you will be working with hot water it is important that children are supervised at all times.

Ingredients needed to make your own copper sulphate crystals:

  • Copper carbonate or black copper oxide
  • Sulphuric acid
  • a clean beaker
  • A conical flask
  • A glass rod
  • A tripod
  • an evaporating dish
  • Gauze
  • Filter paper
  • A funnel
  • goggles
  • Gloves

Instructions on how to make copper sulphate:

  • Using gloves and goggles add sulphuric acid to copper carbonate or copper oxide until no more dissolves.
  • You will know when you have added enough as no more gas will be produced.
  • Filter the solution through the filter paper in a funnel onto an evaporating dish.
  • Heat the solution gently over a bunsen burner until most of the solution has evaporated and allow to cool.
  • crystals of copper sulphate will start to form on the dish.

Notes:

Always wear appropriate personal protection equipment when handling sulphuric acid as it is very corrosive.
