STEP 0: Pre-Calculation Summary

Formula Used

Activity Coefficient = (Ionic activity/Molality)
γ = (a/m)
This formula uses 3 Variables

Variables Used

Activity Coefficient - Activity coefficient is a factor used in thermodynamics to account for deviations from ideal behaviour in a mixture of chemical substances.
Ionic activity - (Measured in Mole per Kilogram) - The Ionic activity is the measure of the effective concentration of a molecule or ionic species.
Molality - (Measured in Mole per Kilogram) - Molality is defined as the total number of moles of solute per kilograms of solvent present in the solution.

What is Ionic activity?

The deviation from ideality of a solute particle-(In this case solute behaves as a
completely dissociated system, that is 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.

How to Calculate Activity coefficient given the ionic activity?

Activity coefficient given the ionic activity calculator uses Activity Coefficient = (Ionic activity/Molality) to calculate the Activity Coefficient, The Activity coefficient given the ionic activity formula is defined as the ratio of the ionic activity of electrolyte to the molality of the solution. Activity Coefficient is denoted by γ symbol.
