Sulfur determination method

...Later research (the molecular formula is (OH) 3 C 6 H 2 COOH) proved the accuracy of Liebig's experimental formula and analysis.
[Halogen and sulfur quantitative analysis]
Many analytical methods have been proposed and are in use for this element, but the flask combustion method by W. Schöniger is currently the most frequently used. The principle is that after combustion in oxygen, the halogen ions or sulfate ions absorbed in an absorbing solution are quantified by titration or other methods.

[ハロゲン・硫黄定量法]
 この元素に関しては多くの分析法が提案され使用されているが,シェーニガーW.Schönigerのフラスコ燃焼法が現在最も頻繁に利用されている。原理は酸素中で燃焼後,吸収液に吸収させたハロゲンイオンまたは硫酸イオンを滴定法などで定量する方法である。…
