【摘要】 用ｐＨ法和气电位法测定氯氧化镁不同温度下在水中的溶解过程。一定间隔时间分析液样中的Ｍｇ￣（２＋）、Ｃｒ￣－、ＯＨ￣－的浓度，用物化方法鉴定固相．得出不同温度下的相转化、溶解的Ｃ～ｔ曲线及动力学方程。计算了它们的Ｋ＿（ｓｐ）和热力学函数．更多还原

【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. TheKsp and thermodynamics functions have been calculated.更多还原
