Description

The conductivity of pure water is not zero, although there are no charged ions solved. This contradiction can be explained with the autoprotolysis of water. Two molecules of water react in an equilibrium reaction to a hydroxide and an hydronium ion. These charged particles lead to a measureable conductivity.

The ion product of water describes this equilibrium reation. The pH scale is based on it. In this experiment, the ion product of water is determined by setting up a galvanic element and using the Nernst equation.
