摘要
运用氢玻璃电极与氯离子膜电极,测定了298.2K下电池(H+)玻璃电极|HCl(m),NAc(W)+H2O(1-W)|(Cl-)膜电极的电动势,并求得了HCl浓度分别为m=0.010,0.020,0.040,0.060,0.080,0.100,0.120时在不同组成(10%~90%)的水-醋酸混合溶剂中的平均活度系数,进而通过多元线性拟合,求得了HCl在不同组成溶剂中的Pitzer参数β0、β1、Cφ。最后对数据处理方法及结果进行了讨论。
By using selective ion electrodes,an EMF measurement is made of the cell glass(H+)|HCl(m),HAc(W)+H2O(1-W)|membrane(Cl-)in a series of HAc-H2O mixtures.The averaged activity coefficients of HCl with the different concentrations such as 0.010,O.020,O.040,O.060,O.080,0.100 and 0.120 mol/kg-solvent are evaluated,and the Pitzer’s parameters β0,β1 and Cφ are obtained as the best fitting coefficients by using the three-parameter-pitzer’s e-quatuin.The date processing aid it results are briefly dealt with.
