Complexometric titration of zinc
Did you know?
WebComplexometric titration (sometimes chelatometry) is a form of volumetric analysis in which the formation of a colored complex is used to indicate the end point of a titration. Complexometric titrations are particularly useful for the determination of a mixture of different metal ions in solution. An indicator capable of producing an ...

These titrations are performed at a basic pH, where the formation constants of Ca-EDTA and Mg-EDTA complexes are high. These types of problems are well-treated …
WebBoric and citric acids were used as a buffer additive. The molar ratio of nickel and zinc ions in the Ni(II)/Zn(II) electrolyte was chosen with a large excess of nickel ions (> 10 times). The chemical composition of the electrolyte was determined by … WebIn a complexometric titration, the formation of a complex is used to indicate the endpoint. This type of titration is very versatile and can be used for a variety of different analytes. Also, because the complex formation is reversible, complexometric titrations can be used to determine the concentration of both acidic and basic solutions.
