使用Fuoss和Bjerrum缔合常数，可以计算离子缔合物发生的体积变化的估计。它的结论是，体积的变化是没有什么用的区分内球和外球复合物，但可能是有价值的区分小抗衡离子的大分子的结合类型。讨论了计算的体积变化与解释电解质溶液超声吸收研究的相关性.在缔合电解质溶液化学研究中出现的最困难的问题之一是外层（溶剂分离）和内层（接触）离子对的实验区别. A.在研究聚电解质的离子结合时也出现了类似的困难，
Using the Fuoss and Bjerrum association constants, estimates of the volume changes which occur upon ionic associates can be calculated. It is concluded that volume changes are of little use in distinguishing between inner-sphere and outer-sphere complexes but may be of value in distinguishing the type of binding of small counterions to macromolecules. The relevance of the calculated volume changes to the interpretation of ultra-sonic absorption studies of electrolyte solutions is discussed.One of the most difficult problems arising in the in-vestigation of the solution chemistry of associated elec-trolytes is the experimental distinction between outer-sphere (solvent separated) and inner-sphere (contact) ion pairs. A. similar difficulty arises in the study of ionic binding by polyelectrolytes where distinction
