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.
