摘要
利用带恒温外壳的高灵敏度密闭式量热计,测量了298.15K下氟化钠在不同组成的正丙醇+水中的溶解焓,溶剂中正丙醇含量是2.5,5.0,7.0,10.0,12.0,15.0,24.4,39.9mol％。电解质氟化钠浓度是0.009～0.043m。在测量结果的基础上,利用德拜-尤格尔第二极限公式,计算了氟化钠在无限稀释溶液中溶解焓。
Enthalpies of solution of NaF in n-propanol and water system have been measured over various ranges of compositions at 298.5k, using high-sensitive, closed calorimeter with isothermal shell and the n-propanol contents were found to be 2.5, 5.0, 7.0, 10.0, 12.0, 15.0, 24.4 and 39. gmol% respectively. The concentration of Sodium fluoride was 0.009～0.043mol. (kgH_2O)^(-1). On the basis of the results obtained, enthalpies of solution of NaF at infinite dilution were calculated with the Second Limiting Equation of Debye-Huckel.
