Karl Fischer titration is a classic titration method in chemical analysis that uses coulometric or volumetric titration to determine trace amounts of water in a sample. It was invented in 1935 by the German chemist Karl Fischer. Today, the titration is done with an automated Karl Fischer titrator. WitrynaThe molar concentration of the solute is sometimes abbreviated by putting square brackets around the chemical formula of the solute. For example, the concentration of chloride ions in a solution can be written as [ Cl − ] [\text{Cl}^-] [ Cl − ] open bracket, start text, C, l, end text, start superscript, minus, end superscript, close bracket .
