Principle

Silver/silver nitrate half-cells are to be prepared, in which the concentrations of silver ions differ in steps of powers of ten. The voltages between the various combinations of these half-cells are to be measured. The evaluation of them is to lead to the Nernst equation.

Learning objectives
