Activity Coefficient Calculator
The Activity Coefficient Calculator is used to calculate the activity coefficient of a solution. The activity coefficient helps describe the non-ideal behavior of solutions, particularly in thermodynamic calculations involving concentration or ionic strength. This calculator assists scientists, engineers, and students in determining the deviation of real solutions from ideal solutions using parameters such as concentration, ionic strength, and interactions between ions.
Formula of Activity Coefficient
The general formula for the activity coefficient (γ) is: γ = exp(-A * z² * √I), where:
- A is a constant depending on the solvent and temperature.
- z is the ion charge.
- I is the ionic strength of the solution.
