Abstract: The dissolution process of oxychlorides in water has been followed by pH andchlorine ion potentiometric determinations, The concentrations of Mg2+, Cl-,and OH- insoluble sarnples were determined and the solid samples were characterized by physical me-thods, The experimental data of the C~t curves have been fitted to kinetic equations.The Ksp and thermodynamics functions have been calculated.

Key words: oxychloride, dissolution-transfomation, kinetics
