Product Description:
Used as an indicator in analytical chemistry, particularly in titrations involving calcium and magnesium ions. It forms a visible precipitate or color change when reacting with certain cations, making it useful in water hardness testing. Also employed in qualitative inorganic analysis to detect the presence of specific metal ions. Its sensitivity to pH and ion concentration allows for precise endpoint detection in volumetric analysis.
