Ionic sphere
WebA series of recent experiments has spurred interest in the charge on glass and silica surfaces of low specific area in pure water, i.e. systems for which the usual picture of the “no salt” regime does not apply. For example, … WebWhen both ions have a complete primary solvation sphere, the ion pair may be termed fully solvated. When there is about one solvent molecule between cation and anion, the ion pair may be termed solvent-shared. Lastly, when the ions are in contact with each other, the ion pair is termed a contaction pair.
