Abstract
비수용액 에틸렌디아민중에서, K-Hg,KI(C1) ∥(C2)KI, Hg-K의 농담전위를 구성하여, 전위차법으로 전위차를 측정하여, Debye-Huckel형의 활성계수식으로 계산한 이론치와 비교한 결과 Marshall-Grunwald 식이 잘 적용되었다.

The dependence of ionic activity and electrode potential upon electrolyte concentration in ethylenediamine includes the effects of ion-pair formation involving all possible combinations of cations and anions represent in the solution and includes the ion-atmosphere effects of dissociated ions. For calculating activity coefficients, Debye-Huckel limiting law, extended Debye-Huckel,equation, and Marshall Grunwald equation were used in comparison of experimental and calculated plots of the electromotive force of the cell versus the logarithum of concentration. The fit of the experimental points to the theoretical curves was improved in case of the Marshall-Grunwald equation.
