Quantitative Determination of Hydrogen

In experiment C2.1.1.2, the hydrogen content of an organic compound is determined quantitatively. Here, too, the combustion analysis is carried out, whereby the carbon is converted to CO2 and the hydrogen is converted to H2O. The water content is determined from the difference in the weight of the drying tube, and the share of hydrogen is determined from the water content.
