摘要
测定了298.2K下0~0.04mol·L-1浓度范围内的NaOAc在10%~90%的乙醇一水、正丙醇一水、乙二醇一水、丙三醇一水及丙酮一水等五种二元混合溶剂中的摩尔电导,并用FOS、Pitts、F-78、L-W等四种电导方程回归出A0、KA、R(或a)等三个拟合多数的数值。最后就四个方程的适用性,A0与溶剂组成的关系,NaOAc在不同溶剂中的缔合情况及溶质一溶剂相互作用进行了讨论。
The molar conductances of sodium,acetate in 1 0%~90%concentration range mixtures of EtOH.H20,1-prOH-H2O,En(OH)2-H2O,Glycerol-H2O and Me2CO-H2O at 298.2K are deter-mined in this paper.The best fitting parameters , such as A0,KA and B(or a)are regressed from Fuoss-Onsager-Skinner, Pitts,Fuoss-1978 and Lee-Wheaton conductance equations.Adiscussion about the adaptable of these four conductance equations,the relationship between A0 and the component of the mixtures,the ion association and solvation of NaOAc in different solvents and Walden product A0 are glven
