The titration performed by adding a known volume of a standard solution of potassium iodide (KI) to the sample. Therefore the iodine generated by the reaction between KI and water titrated with a standard solution of sodium thiosulfate (Na2S2O3). The concentration of the standard solution known, and the volume of titrant required to reach the endpoint of the reaction can also used to calculate the amount of water in the sample.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Karl_Fischer_Titration_Equipment\"><\/span>Karl Fischer Titration Equipment<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Karl Fischer titration equipment used to determine the amount of water in a sample.

The titration vessel filled with the sample to tested and the burette filled with the Karl Fischer titration reagent. The burette then attached to the titration vessel and the Karl Fischer titration reagent is allowed to flow into the sample.

However the principle behind the Karl Fischer titration is that the water in the sample will react with anhydrous potassium iodide (KI) to form potassium iodide (KI) and water. The water content of the sample then determined by measuring the amount of iodine that produced. The Karl Fischer titration can used to determine the water content of a wide range of samples, including solids, liquids, and gases.<\/p>\n<p>The procedure for the Karl Fischer titration is as follows:<\/p>\n<ol>\n<li>A known volume of the sample transferred to a flask.<\/li>\n<li>Anhydrous potassium iodide (KI) added to the flask.<\/li>\n<li>The flask then heated to a gentle boil.<\/li>\n<li>The iodine that produced then measured.<\/li>\n<\/ol>\n<p>The applications of the Karl Fischer titration include the determination of the water content of pharmaceuticals, the water content of foods, and the water content of fuels. The preparation of the Karl Fischer titration involves the use of anhydrous potassium iodide (KI) and anhydrous sodium carbonate (Na2CO3). Therefore the advantages of the Karl Fischer titration include its accuracy and its ability to determine the water content of a wide range of samples. The disadvantages of the Karl Fischer titration include its time-consuming nature and its reliance on boiling<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Karl_Fischer_Titration_Reagents_and_Applications\"><\/span>Karl Fischer Titration Reagents and Applications<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<ul>\n<li>Karl Fischer titration a volumetric analytical technique that used for the determination of the water content of a substance.
