HYDROXY NAPTHOL BLUE indicator for calcium determination is make by Dissolve 0.3 g in 100 mL of water, add 10 mL of 1 N sodium hydroxide volumetric solution and 1.0 mL of calcium chloride solution (1 g in 200 mL), and dilute with water to 165 mL.

Use. Murexide is used in analytical chemistry as a complexometric indicator for complexometric titrations, most often of calcium ions, but also for Cu, Ni, Co, Th and rare-earth metals. It functions as a tridentate ligand. Its use has been eclipsed by calcium-ion selective electrodes.
