Principle

Electrical voltages are not only measurable between different metals in solutions of their salts, but also between half-cells which are the same except for containing different concentrations of the salt solution. Such couples of the same half-cells with different salt concentrations are called "concentration series". In this experiment a potassium chloride solution concentration series is prepared and the voltages measured. Two silver/silver chloride electrodes serve as electrodes.


Learning objectives

  •  How to build galvanic cells
  • Potential of series of concentration

 

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
