Applications: Complexometric Titrations: Calcon is primarily used as an indicator in complexometric titrations to determine the concentration of metal ions, particularly calcium (Ca2+). It forms a complex with calcium ions, resulting in a color change from red to blue. The color change helps in determining the endpoint of the titration.Water Hardness Testing: Calcon is often employed in water analysis to determine the hardness of water, which is mainly caused by the presence of calcium and magnesium ions. The dye reacts with calcium ions in water, producing a color change that can be quantitatively measured to determine the hardness level.Photometric Determination: Calcon can be used in photometric determinations to measure metal ion concentrations in various samples. The intensity of the color change can be correlated to the concentration of the metal ions, allowing for quantitative analysis.Indicator in Biochemical Assays: Calcon is utilized as an indicator in various biochemical assays to detect and measure metal ions. It can be used, for example, to determine calcium concentrations in biological samples or to monitor metal ion fluxes in cellular processes.
