Study Notes
Complexometric Titration
- The purpose of complexometric titration is to determine the concentration of metal ions in a solution by reacting them with a chelating agent.
Indicators in Complexometric Titration
- Eriochrome Black T is a commonly used indicator in complexometric titration.
Role of Chelating Agents
- A chelating agent, such as EDTA, forms a stable complex with metal ions, allowing them to be quantitatively determined.
Characteristics of Complexometric Titration
- The primary characteristic of complexometric titration is the formation of a stable complex between the metal ion and the chelating agent.
EDTA as a Titrant
- EDTA is commonly used as a titrant in complexometric titration because it can form a stable complex with a wide range of metal ions, and its concentration can be accurately determined.
