Year 13 chemistry students have done their first experiment of this school year!
They used various metals (copper and zinc) and their ion solutions to make an electrochemical cell aka., a battery. In addition, they used a salt bridge to complete the circuit. This way allowed the flow of electrons between the half cells.
They attached the circuit system to a voltmeter. It was in order to measure the voltage created by the flow of electrons and so to calculate the different electrode potentials (emf).
