In this paper, the effect of magnetized water on the stability constant Kst, oscillation strength f, molar extinction coefficient εmax and Gibbs free energy ΔG for complexes was investigated. Complexes of Eriochrome black T (EBT) as a ligand with Ca2+, Mn2+, and Zn2+ ions were prepared for this purpos. The stability constant values of the complexes found to be decreased by using magnetic water in their preparation except for EBT-Ca complex. Both Ca2+ and Mn2+ ions showed deviation from Irving-Williams order. The oscillation strength shows the type of spectrum is absorption spectrum for all complexes and in both in magnetized and non-magnetized water. εmax found to be increased by using magnetized water over than non-magnetized water. The stability constants for the complexes calculate analytically by applying jobs method and Yoe and Jones method.
