Webb5 okt. 2024 · Estimation of Hard Water: Traditionally, hardness in water is estimated by complexometric titration using sodium salt of EDTA and EBT as indicator at pH = 9-10. EBT forms an unstable wine-red colored complex with Ca2+/Mg2+ions, which upon titrating with EDTA, results in the breaking of EBT-Ca2+/Mg2+ unstable bond and formation of … WebbWhat is complexometric titration – Definition. Gerold Schwarzenbach introduced complexometric titration in 1945. It is defined as the titration of an analyte solution …

WebbComplexometric titration is a quantitative analysis in which the formation of a colored complex is used to indicate the end point of a titration. This method uses a very large molecule called EDTA which forms a complex … WebbA redox titration [1] is a type of titration based on a redox reaction between the analyte and titrant. It may involve the use of a redox indicator and/or a potentiometer. A common example of a redox titration is treating a solution of iodine with a reducing agent to produce iodide using a starch indicator to help detect the endpoint.
