Ni۲+ and UO ۲۲+ ions ,Potentiometric stud y of complexation between Zn۲+ with chel-a acr proton transfe r and com paring w ith solid state res ults

The pro tonation c onstants of chelidamic acid(chel) and ۹-Ami noacridine (aacr), in all of the probability protonated forms, the equilibrium con stants for the chel-aacr proton transfer system and the sto ichiometry and stability constant of the com plexation of this system with UO۲۲+, Zn۲+and Ni۲+ ions in ۵۰% dioxane-۵۰% water (V/V) solvent were investig ated by potenti ometric pH titration method. T he stoichiometry of the most complex species in solutio n were compared with corresponding crystalline metal io n complex es.
