The 12 pages that link to Chemical activity, each with the reason it gives.

• Chemical equilibriumRelated: Equilibrium expressions are fundamentally written using activities, not raw concentrations.

• Chemical potentialRelated: Activity is the composition variable used inside chemical-potential expressions.

• Solubility productRelated: Activities, rather than raw concentrations, define the rigorous Ksp expression.

• Equilibrium constantBroader topic: The thermodynamic equilibrium constant is defined using activities rather than raw concentrations.

• Acid–base equilibriumRelated: Thermodynamic equilibrium constants use activities rather than raw concentrations.

• Henderson–Hasselbalch equationRelated: Activities, rather than concentrations, give the more general thermodynamic form of the relationship.

• Activity coefficientRelated: The coefficient converts composition into this effective thermodynamic quantity.

• Ionic strengthCompared with: Ionic strength is a solution property; activity describes an individual species’ effective concentration.

• Law of mass actionRelated: Thermodynamic equilibrium expressions use activities rather than raw concentrations for nonideal mixtures.

• Reaction quotientBroader topic: Activities, rather than raw concentrations, define Q thermodynamically.

• PotentiometryRelated: Electrode response generally tracks ion activity rather than concentration alone.

• Concentration cellBroader topic: The cell responds to activity differences, which can diverge from measured concentration differences.
