Thermodynamic properties of ions in solution - activity calculation

Due to the interaction between ions in solution, the concept of concentration is inadequate.Thus, the term activity click here is a more appropriate concept, as it takes into account the activity coefficient of ions, which are very well estimated in dilute solutions, and has values between 0 and 1.The presence of strong interaction between ions in electrolyte solutions causes the thermodynamic read more properties to be different from non-electrolyte solutions, that is, optimal solutions have a certain deviation from that concept.Different models are described to determine the activity coefficients in concentrated solutions.
