History of Karl Fischer Titration •Karl Fischer (March 24, 1901 – April 16, 1958) was a German chemist •Published a method in 1935 to determine trace amounts of water in samples. The objective of this exercise is to prepare and accurately determine the concentration of a solution of NaOH, and to use that standardized solution in the determination of the concentration of acid in a commercially available sample. In its simplest form ‘doing a titration’ (titrimetric analysis) is a practical method for determining the concentration of a solution of a known compound. This method for quantitative chemical analysis was developed by the German chemist Karl Fischer in the year 1935, Today, specialized titrators (known as Karl Fischer titrators) are available to carry out such titrations.
