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
- 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.
