摘      要：正The component solubility of HCl-MgCl2-H2O system at 50℃ was calculated by using Pitzer’s ion-interaction model and its extended HW model. The values of the parameters of β（0）, β（1）,C（?） of HCl and MgCl2 were obtained from optimization of the literature data, and θMgH and ψMgHCl were derived by coupling activity coefficient with solubility data. The comparison between the results by using the
