在混合溶剂电解质活动及相关系数偏摩尔热力学性质的解决方案的重要参数。活动的规定,体现了溶剂系数之间的交互作用的分子,而solvent-ion相对偏摩尔属性反映实际偏摩尔性质的解决方案和标准偏差电解质的状态。bio-chemica的发展、有机盐溶液热力学性质和判定的关注。他们是离子溶液、离子协会和解决结构理论的研究和应用具有重要的意义。有机盐溶液和决心的热力学性质的关注。
在这篇文章中,电导率测定303 K的盐,NaBr混合溶剂,在水里,乙醇-丙酮)的电导率和粘度混合溶剂进行计算,探讨了NaBr,在一个混合溶剂(水-乙醇-丙酮)、活动及相关系数偏摩尔自由能量,讨论了活动的电解质溶液浓度和系数相对偏摩尔自由能量。结果表明:在一定的温度、有机溶剂,以降低浓度、盐/ NaBr /奈在混合溶剂(水、-乙醇-丙酮)的活动。浓度增加,盐/ NaBr /奈相对偏摩尔自由能值增加(减少)的负面,在一定浓度、温度、锂盐/ NaBr /奈溶液活度系数和相对偏摩尔免费能源和水的混合物克分子数增加。

In the mixed solvent electrolyte activities and related coefficient partial molar thermodynamic properties of solution of important parameters. The activity, the coefficient of solvent, the interaction between the molecules, and solvent - ion relative partial molar attribute the actual partial molar properties of solution and the standard deviation of the electrolyte. Bio - chemica development, orgainc salt solution thermodynamics properties and judgement. They are ions, ion association and solve structure theory research and application of important significance. Organic salt solution and determination of the thermodynamic properties.
In this article, the conductivity of salt, determination of 303 K NaBr mixed solvents, in the water, ethanol - acetone) of conductivity and viscosity mixed solvents, discusses the calculation NaBr, in a mixed solvent (water - ethanol - acetone), and the correlation coefficient partial molar free energy, discusses the electrolyte solution concentration and activities of relative partial molar free energy coefficients. The results show that a certain temperature, organic solvents, in order to reduce concentrations, salt/NaBr/in mixed solvent (water, - ethanol - acetone) activities. Increasing concentration, salt/NaBr/relative partial molar freedom can increase (decrease) of value in certain negative, concentration, temperature, lithium salts/NaBr/solution activity coefficients and the relative partial molar free energy and water mixture mole fraction increases.

Electrolyte in the activity coefficients mixed solvents and relative partial molar nature is an important parameter of the solution thermodynamics research. Activity coefficients reflects the designated solvent ions and solvent molecules, and the interaction between the relative partial molar nature reflect the actual electrolyte solution with standard partial molar properties of deviation. Along with the development of biological chemistry, organic water salt solution thermodynamics properties were studied, and more and more attention. They solvent, ion for ions associating and solution structure theory research and application of important significance. Water and salt solution thermodynamics properties of organic matter and the determination of more and more attention.
This method in 303 K applied electric NaBr NaCl, when measured in mixed solvent (NaI, water - ethanol - the conductivity, and acetone), the viscosity of mixture calculated the NaCl, NaBr NaI, in mixed solvent (water - ethanol - acetone) of its relative partial molar

activity coefficients, discusses the freedom to the concentration of electrolyte solution activity coefficients and relative partial molar freedom can influence. The results show that a certain temperature solvent, the decrease with solution concentration, NaCl/NaBr/NaI in mixed solvent (water - ethanol - acetone) of activity coefficients increased. Increasing concentration, NaCl/NaBr/NaI relative partial molar freedom can increase (decrease) negative values, in certain concentration, temperature, NaCl electrolyte solution NaBr/NaI/the activity coefficients and the relative partial molar with mixed solvent free to the mole fraction of water increases.
