In this method, a coloured complex is formed, indicating the end point of the titration. Complexometric Titration is said to be achieved if a kind of complex molecule is formed between the analyte and the titrant till the end of the reaction is acquired. Complexometric Titration: This type of titration can also be referred to as chelatometry. Multiple choice questions on principles,complexing agents,masking agents, stability of complex, methods of titration and indicators in complexometric titrations-Page-5 Indicator used in complexometric titration … Mohr method of determination of chlorides by titration with silver nitrate is one of the oldest titration methods still in use - it was researched and published by Karl Friedrich Mohr in 1856. Stability constant of calcium complex is a little bit higher, so calcium reacts first, magnesium later. Complexometric indicator: water soluble organic molecules that undergoedefinite colour change in the presence of specific metal ions and are used incomplexometric titrations. The complexes are formed by the reaction of a metal ion (an acceptor, a central atom or a cation) with an anion, a neutral molecule or very rarely a positive ion. Applications of Complexometric Titrations Complexometric Titrations are useful in a couple of different fields, namely analytical chemistry and the pharmaceutical sciences. The end point is determined by plotting the P M value which is the negative logarithm of the metal ion concentration versus volume of the titrant. APPLICATION OF COMPLEXOMETRIC TITRATION :-To determine the concentration of metal ions in solutions. Direct method The solution containing the metal ion to be determined is buffered to the desired pH (e.g. The idea behind is very simple - chlorides are titrated with the silver nitrate solution in the presence of chromate anions.
