- 中文摘要: E. M. F. of the Cell, Cd-Hg (2-phase)/CdAc2(m), Hg2Ac2(s)/Hg was measured at 20°, 25°, 30° and 40℃. The standard e. m. f. of the sell, Cd/CdAc2(m), Hg2Ac2(c)/Hg was evaluated as E°=1.1500- 11.09×10¯4T+1.06×10¯6T2. The thermodynamic data of the reaction, Cd(c)+Hg2Ac2(c)=2Hg(I)+Cd++(aq)+2Ac¯(aq) at 25℃ were estimated as ⊿F°=-43,139, ⊿H°=-48,698 cal mole¯1 and ⊿S°=-22.0 cal deg¯1 mole¯1 at 25℃. The thermodynamic data for the formation of Hg2Ac2(s) were evaluated as ⊿F..°=-202.3, ⊿H..°=-154.5 Kcal mole¯1 and S°=72.9 cal deg¯1mole¯1. From measurements of the heats of solution of CdAc2.2H2O in aqueous solution, the relative partial molal enthalpies of cadmium acetate in aqueous solution were estimated.
