- Practical procedures for estimating metal ions using complexometric titration
- Understanding the principles behind indicator selection and pH control in complexometric titrations
Zusammenfassung der Kapitel (Chapter Summaries)
The handout begins by defining complexometric titrations, highlighting their use in estimating metal ions by forming complexes with a complexing agent, typically EDTA. The basic principle of EDTA's function as a hexadentate ligand in complex formation is explained. A detailed discussion on the preparation of solutions and reagents, including EDTA, zinc sulfate, stock solutions of various metal ions, buffers, indicators, and other necessary chemicals, is provided. The document then delves into the estimation of calcium and magnesium ions present in a given stock solution using EDTA. This section outlines the procedures and calculations involved in complexometric titration using EDTA as a complexing agent.
