The factor relating activity to a selected concentration or fraction scale, thereby encoding departures from the corresponding ideal reference.

This is an authored directed relation from the source endpoint to the target endpoint.
An activity coefficient parameterizes the ratio between activity and a stated composition measure under a chosen standard-state convention; its value is model, scale, state, and mixture dependent.
The target represents a state, property, observable, or state-dependent description associated with the source system or theory.

Ionic strength is a central variable in dilute-solution activity-coefficient models, but solvent composition, ion size, specific interactions, temperature, and model range also matter.
A theory, law, or interaction describes the behavior of the target within a stated regime. The edge detail must state important limits or qualifications.
