The solubility on any substance in water may be classified as : Molecular ability: AB(s/l/g) overset(aq)iffAB(aq) Ionic solubility : AB (s/l/g) overset(aq)iff A^(+)(aq)+B^(-)(aq) For a substance AB(s) the following thermodynamic informations are available at 300K: Molecular solubility: Delta H^(@)=+20kcal/mol, DeltaS^(@)=+40kcal/K-mole Ionic solubility: DeltaH^(@)=-25 kcal/ mol, DeltaS^(@)=-50 cal/K-mole The equilbrium constant for the ionic and molecular solubility of AB(s) in water at 300K are respectively:
