http://large.stanford.edu/courses/2015/ph240/dodaro1/ WebKarl Fischer titration is an analytical technique to measure the amount of water contained in various samples, which may be solid, liquid or gaseous. This method was originally developed in the 1930s by German chemist Karl Fischer. Karl Fischer titration is based on a 1:1 reaction between iodine and water in the presence of sulfur dioxide and a ... WebJun 29, 2024 · Concentrated sulfuric acid is often used as a catalyst in Fischer esterification reactions. To my knowledge, the role it plays in the reaction is not as a reducing agent or dehydrating agent but only serves the role of creating an acidic environment, as seen in the mechanism. Thus, dilute sulfuric acid would be sufficient. datentyp python
