Expression of the salt effect that relates the change in solubility of a nonelectrolyte (e.g., gas or organic liquid) to changing ionic strength of aqueous solutions, \[\lg (s_{\rm{o}}/s) = K_{s} I_{s}\] where \(s_{o}\), \(s\) are the solubilities of nonelectrolyte in pure water and saline solution, respectively, \(K_{s}\) the Sechenov parameter (an empirical proportionality constant), and \(I_{s}\) the ionic strength of the saline solution.
Notes:
- Positive values of the Sechenov parameter correspond to the commonly observed salting-out effect; negative values to the less common salting-in effect.
- Sechenov is the international and Setschenow the German transliteration of Сеченоь.
