What is the mean activity coefficient?
The mean activity coefficient is determined from measurements of such properties of solutions as freezing point, vapor pressure, solubility, and electrical potential. Figure 6 shows the mean activity coefficients for a number of salts as a function of molality. Note that ?± is equal to 1.0 at infinite dilution.What is the mean activity coefficient of Debye Huckel?
Debye and H?kel developed the following equation to calculate the mean ionic activity coefficient ?±: log?±=?1.824?6(?T)3/2?z+z???I.What is the mean activity coefficient for an ideal solution?
In an ideal solution the activity coefficient = 1, and the activity of the component is equal to its mole fraction. In general, the greater the amount of dissolved material, the lower the activity coefficients of each of the species present.- Definition. The activity of a chemical entity is a dimensionless quantity derived by multiplying a correction factor (called an activity coefficient ) by some measure of its molar abundance, such as molar concentration (molarity), molality, partial pressure, or mole fraction.
