Electrolytic solution, Activity coefficient, ActivityAbstract
Due to the interaction between ions in solution, the concept of concentration is inadequate. Thus, the term activity 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 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.Downloads
