Product Description:
Used as a complexometric indicator in titrations involving EDTA, particularly for determining hardness of water. It changes color from wine red to blue when metal ions like calcium and magnesium are chelated by EDTA, signaling the endpoint of the titration. Commonly applied in water quality testing and industrial water treatment processes to monitor and control scale formation. Also used in educational labs to demonstrate complexometric titration techniques.
