Karl fischer is an analytical technique used to measure the moisture (water) content in solids, liquids or gases. Karl fischer titration has become one of the most widely used techniques for the determination of water content in a variety of substances El hidrógeno producido en el cátodo es muy buen agente reductor Muestras fácilmente reducibles (nitro compuestos) son reducidas, produciendo agua Celda más fácil de limpiar No recomendado para muestras fácilmente reducibles
The titrimetric determination of water by the karl fischer method depends on the reaction that takes place quantitatively between water and a reagent consisting of sulfur dioxide and iodine in anhydrous pyridine and usually methanol. The technique most commonly used for these analyses because of its rapidity, accuracy and ease of use is karl fischer titration The titration is based on the oxidation of sulphur dioxide by iodine in the presence of water. The karl fischer procedure is a titration method used for the quantitative determination of water content in liquids and solids Karl fischer titration is used in a variety of areas, e.g For determining the water content of groceries, chemicals, pharmaceuticals, cosmetics and mineral oils.
The technique was developed by a chemist named karl fischer
