uses of  eriochrome

Complexometric Titrations:

EBT is widely used as an indicator in EDTA titrations to determine the concentration of metal ions in solutions. It changes color from blue to red when it binds with metal ions like calcium and magnesium, making it essential for water hardness analysis.

Water Hardness Testing:

EBT helps measure the hardness of water by indicating the presence of calcium and magnesium ions. The color change during titration allows for accurate quantification of these ions.

Determination of Metal Ions:

It is used to detect and quantify various metal ions in different samples. This application is crucial in environmental testing, pharmaceuticals, and quality control in industries.

Buffer Solutions:

EBT is sometimes used in buffer solutions to maintain the pH at a specific level during titration processes.

Indicator for Complexes:

It serves as an indicator for various metal-ion complexes in research and industrial applications.

Educational Demonstrations:

EBT is commonly used in educational laboratories to demonstrate titration techniques and the principles of complexometric analysis to students.
