These values were measured with an a.c. potentiometer. The results show the sedimentation potential varies in proportion to the atomic weight of a cation to the weight of a fixed anion and vice versa. From this relation, it is shown that the absolute value for an ionic partial molar volume can be determined without any assumption as to the value for given ions or the ratio of values for any pair of ions. Therefore, the ionic partial molar volume of the fixed simple monovalent ions can be calculated from the convergent value of the sedimentation potential obtained by approching the atomic weight of the unfixed ion to zero. In this way the ionic partial molar volume for 9 kinds of ions was obtained. The ionic partial molar volume for 2 kinds of ions was calculated keeping the partial molar volumes of chloride ion as a standard.}, pages = {155--162}, title = {1価-1価電解質水溶液におけるイオンの部分モル容積の決定法}, volume = {26}, year = {1984} }
