Karl Fischer Titration

Reagents & Chemicals

The term "Karl Fischer Titration" can be traced back to the beginnings of the quantitive determination of water in 1935. The "Karl Fischer method" was practiced for the first time by German chemist Karl Fischer and manifested itself in several pharmacopoeias since then.

Initially water was titrated with an anhydrous methanolic solution of iodine, sulfur dioxide and pyridine in this method. In 1982 Eugen Scholz changed this procedure by adding basic components such as imidazole or acidic components such as salicylic acid. This modified method is still an essential part of everyday laboratory work.
