| activity coefficient |
the ratio of the activity (of an electrolyte) as measured by some property, such as the depression of the freezing point of a solution, to the true concentration (molality). It is usually less than 1 and increases as the solution becomes more dilute, approaching unity at infinite dilution, when the attractive forces between oppositely charged ions become negligible.

| activity coefficient |
A measure of the extent to which substances, on dissolving in water, form charged ions or associate to form multiple molecules; the amount dissolved influences colligative effects, such as equilibrium freezing point depression of solution drops and reaction rates in solution.

| activity coefficient |
A ratio of the activity of species i(ai) to its molality (C). It is a correction factor which makes the thermodynamic calculations correct. This factor is dependent on ionic strength, temperature, and other parameters.
