Description

In experiment C1.3.1.1, water is analyzed by electrolysis in the Hoffmann voltameter. The transformation of electrical energy into chemical energy is demonstrated at the same time. First the gases generated - hydrogen and oxygen - can be determined qualitatively. Quantitative assessment of the quantities of gas generated can then be used to derive the chemical formula for the compound water.
