Principle

In exactly the same way as metals, nonmetals also develop different solution pressures and so different potentials, as soon as they can form redox systems in appropriate solvents. In this experiment students prepare a simplified standard hydrogen electrode and also oxygen, chlorine, bromine and iodine half-cells. These half-cells are then to be combined to galvanic cells and their standard potentials measured.
