Equilibrium studies of the mixed ligands complexes of calcium (II) ion with drug phenylpropanolamine hydrochloride as primary ligand and the amino acids viz. glutamine and phenylalanine as secondary ligand were determined pH metrically at 30oC at ionic strength of 0.1 M NaClO4 in 80% (v/v) ethanol-water medium. Formation of complex species with respect to pH have been discussed by Irving-Rossotti technique and evaluated by SCOGS computer program.
