Nonmetal galvanic cells

Article no: P7400900

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.

 

Learning objectives

  •  How to build nometals galvanic cells
  • Combination of oxygen and chlorine and iodine half-cells

 

Benefits

  • Easy teaching and efficient learning by using interactive experimentation PHYWE-Software
  • Experiment is part of a complete solution set with experiments for the topic Electrochemistry matched with international curriculum: all topics are covered
