Use this demonstration to find the value of the Faraday constant from electrolysis of copper(II) sulfate solution. Includes kit list and safety instructions.

In this experiment, students learn how the value of the Faraday constant – the amount of electric charge carried by one mole of electrons – may be determined by using weighed copper electrodes to carry out the electrolysis of aqueous copper(II) sulfate.
