The students know that metallic conductors do not change chemically when current passes through them. This experiment should bring them to the realisation, that the chemical composition of a liquid conductor does change when electrical current passes through it.


  • No additional cable connections between the building blocks needed - clear arragned and quick setup
  • Contact saftey due to puzzle blocks system
  • Corrosion-free gold plated contacts
  • Doubled earning sucess: Electric circuit diagram on top, real components can be seen unterside


Do the chemical properties of a conducting liquid change when current is passing through it?

Conduct electric current through an aqueous solution of sodium sulphate and observe if this thereby changes chemically.
