Description

In experiment C4.4.5.1 the voltage during an electrolysis is raised starting from zero. Note that there is no significant flow of current until a certain voltage level is reached. That voltage is called the decomposition voltage or the deposition voltage. It is the combination of the polarisation voltage and the overvoltage. Both parameters depend on the electrode material. Different electrode materials are investigated in experiment C4.4.5.1.
