It is the most common method because it is accurate and cost efficient. In a complexometric titration, the detection of the endpoint can be observed by the two methods. are some examples of complexometric indicators. Calcein, curcumin, Eriochrome Black T, fast sulphon black, hematoxylin, etc. These indicators are organic molecules that are soluble in water. These indicators are also known as pM indicators or metallochromic indicators. These indicators undergo a definite colour change in presence of specific metal ions. are used in the complexometric titration.Ĭomplexometric indicators are those indicators that are used in complexometric titrations. Indicators such as calcein and Eeriochrome black T etc. It is a volumetric analysis as the volume of the analyte, titrant, and even indicator play an important role during titration. In this type of titration, an indicator is used which is capable of producing clear colour change in titration which indicates the endpoint of the titration.Ĭomplexometric titrations are used for the determination of the concentration of metal ions in the solution. Those volumetric titrations or analyses in which the endpoint is indicated by a coloured complex, are known as complexometric titrations. So, let's discuss this technique in detail. Do you know the drugs used for the treatment of diabetes contain metals in a specific amount and the metal content in a drug can be determined by complexometric titrations! It is a very useful, simple, and low-cost technique for various medicinal applications in the pharmaceutical field. It is mainly useful for the determination of a mixture of different metal ions in solution.Īs we all know, the number of diabetes patients is increasing day by day worldwide. Complexometric titration is a volumetric analysis where the endpoint of the analysis or titration is identified by the formation of a coloured complex.
