| 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.
