...Debye et al. assumed that strong electrolytes are completely ionized in solution, and quantitatively examined how electrostatic Coulomb forces act between ions and how they affect the thermodynamic properties and migration speed of ions. When calculating the distribution of other ions around each ion according to this theory, it is found that each ion behaves as if it is surrounded by a group of ions with the opposite charge, known as an ionic atmosphere. According to this theory, for example, the permeability coefficient g , activity coefficient f , and molar conductivity Λ of a strong electrolyte in solution are given by the following equations: *Some terminology explanations that mention "ionic atmosphere" are listed below.

…そこで,デバイらは,溶液中で強電解質は完全に電離していると仮定し,イオン相互の間に静電的なクーロン力が働くことを考慮して,それがイオンの熱力学的な性質や移動速度などにどのような影響を及ぼすかを定量的に検討した。この理論に従って個々のイオンのまわりの他のイオンの分布を計算すると,個々のイオンは,全体としてそれと反対の電荷をもつイオンの集団,いわゆるイオン雰囲気ionic atmosphereでとり囲まれているような挙動をすることがわかる。この理論によると,たとえば,溶液中における強電解質の浸透係数g,活動度係数f,モル導電率Λがそれぞれ次式で与えられる。… ※「ionic atmosphere」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
