Abstract: The stability constants of palmitic acid complexes with Mn (II), Co (II), Ni (II), Cu (II) and Zn (II) have been studied using pH measurements in 70 % (v/v) ethanol-30 % (v/v) water medium. The values of proton-ligand stability constant (pK) and metal-ligand stability constant (logK) of binary complex is calculated using Irving-Rossotti titration technique.

Keywords: stability constant, ethanol-water mixture, pHmetric method
