Bromley equation
The equation can be written, in its simplest form for a 1:1 electrolyte, MX, as is the mean molal activity coefficient. He noted that the equation gave satisfactory agreement with experimental data up to ionic strength of 6 molal, though with decreasing precision when extrapolating wikipedia.org

Ionic strength
Ionic strength can be molar (mol/L solution) or molal (mol/kg solvent) and to avoid confusion the units should be stated explicitly. Both molar and molal ionic strength have been used, often without explicit definition. Debye length is characteristic of the double layer thickness. wikipedia.org

Nernst equation
For a given dissolved species, its chemical activity (a) is the product of its activity coefficient (γ) by its molar (mol/L solution), or molal (mol/kg The formal reduction potential makes possible to more simply work with molar (mol/L, M) or molal (mol/kg , m) concentrations in place of activities. wikipedia.org

Specific ion interaction theory
The activity coefficient of the jth ion in solution is written as γj when concentrations are on the molal concentration scale and as yj when concentrations (The molality scale is preferred in thermodynamics because molal concentrations are independent of temperature). wikipedia.org

重量摩尔浓度
重量摩尔浓度为3mol/kg的溶液可表示为“3 molal”或“3 m”。但是随着国际单位制的使用，美国在量度方面的权威机构美国国家标准技术研究所认为“molal”和单位符号“m”已经过时，建议使用mol/kg及其相关国际单位制的单位来表示。 wikipedia.org

盐湖盐类水溶液298.15k时稀释热和表观摩尔焓的研究
The heat of dilution of aqueous solution of the chloride (KCl, NaCl, MgCl2,CaCl2) and sulfate (Na2SO4, K2SO4, MgSO4) of Salt Lakes were measured over a concentration range of 0.05-2.1mol•kg-1 at 298.15K. The data were extrapolated to infinite dilution by use of the Debye-Huckel limition law to obtain relative apparent molal enthalpies (ФLi).
