Applications:
Metal Indicator: Eriochrome Cyanine R is primarily used as a metal indicator in complexometric titrations. It forms stable complexes with metal ions, particularly calcium, magnesium, and other transition metals. The dye undergoes a color change upon complex formation, allowing for the determination of metal ion concentration in a solution.Water Analysis: Eriochrome Cyanine R is commonly employed in water analysis and testing, specifically for the determination of water hardness. Hard water contains high concentrations of calcium and magnesium ions, and Eriochrome Cyanine R helps in the quantitative analysis of these ions.Photometric Analysis: The dye is also utilized in photometric analysis to measure the concentration of metal ions in solution. The color intensity or absorbance of the complex formed between Eriochrome Cyanine R and the metal ion is measured, providing a quantitative assessment of metal ion concentration.pH Indicator: Eriochrome Cyanine R can act as a pH indicator due to its pH-dependent color changes. It appears yellow in acidic conditions and transitions to blue-violet in alkaline environments. This property makes it useful for pH measurements and as an indicator in various chemical assays.
