溴化钠在正丙醇-水混合溶剂中溶解热和溶剂化热
Enthalpies of Solution and Solvation of NaBr in Aqueous Mixtures of n-propanol
【摘要】 用高精度等温外壳式量热计测量了298．15K下NaBr在不同组成正丙醇水混合溶剂中溶解热，根据测量结果及以前作者对NdCl3，BaCl2；NaCl，Nal，NaF／n－C3H7OH－H2O体系溶解热的研究结果，计算T298．15K下，正丙醇水混合溶剂中，上述盐的标准溶解热和NaF，NaCl，NaBr和NaI的溶剂化热．讨论了电解质溶解热和溶剂化热与离子特性、混合溶剂的组成和结构的关系．
【Abstract】 Enthalpies of solution of NaBr in aqueous ndxtures 0f n-propanol has been measures over various ranges of compositions at 298.15 K, using high-sensitive calorime ter with isothermal shell. On the bases of the results obtained and our former work for the systems NdCl3, BaCl2, NaCl, NaF, and NaI/n-propanol-water, standled enthaJpies ofsolution of afoementioned salts and enthalpies of solvation of soditlm halide in aqueous thextures of n-propanol were calculated. The dependence of enthapies of sulution and solvation of the electrolytes on the nature of ion, composition and structure of the mixed solvents was discussed.
