GENCATVOL28_Section5_TitrationSystems_Layout 1 7/19/11 2:55 PM Page 5.2 Titration Introduction Titration is a quantitative measurement of an analyte in solution by it’s complete reaction General procedure used without a reagent. Titration is used in analytical chemistry to determine the amount or in manual titration concentration of a substance. In a titration, one reagent (the titrant) is slowly added to a solution containing the species being measured (the analyte). As it is added, a chemical Before starting, make sure that ...
Acid-Base Titration Lab Introduction In chemistry laboratory, it is sometimes necessary to experimentally determine the concentration of an unknown acid or base solution. A procedure for making this kind of determination is called an acid-base titration. In this laboratory process, a solution of known concentration, called the standard solution, is carefully added to a solution of unknown concentration until the mixture becomes neutral. The neutral point of the solution is recognized by an indicator’s color change. If the unknown ...
Nitrogen Determination by Kjeldahl Method Nitrogen Determination by Kjeldahl Method The Kjeldahl method is used to determine the nitrogen content in organic and inorganic samples. For longer than 100 years the Kjeldahl method has been used for the determination of nitrogen in a wide range of samples. The determination of Kjeldahl nitrogen is made in foods and drinks, meat, feeds, cereals and forages for the calculation of the protein content. Also the Kjeldahl method is used for the nitrogen determination ...
