What is Ionic Activity?

The deviation from ideality of a solute particle-(In this case solute behaves as a completely dissociated system, that is a strong electrolyte) can be expressed in terms of solute activity, denoted by the letter ‘a’. Activity is defined as a measure of the effective concentration of a molecule or ionic species. Activity depends on the temperature, pressure and composition of the mixture of species. Activity of a solute depends on its concentration, being proportional to concentration at sufficient dilution.
