Dilatometer Studies of the Apparent Molar Volume Limiting Law for High-Charge Electrolytes
Keyword(s):
A continuous-dilution dilatometer, of the tilting type, specifically designed for study of the apparent molar volumes of aqueous electrolytes at low concentrations, is described. Results at 298.16 K have been secured for multivalent (� 3, � 4, � 6) univalent electrolytes which demonstrate that the apparent molar volumes vary with c� in approximate conformity with the Debye-Huckel limiting-law slopes. Data are presented for: [Co(en)3] Cl3, K3 [CO(CN)6], [Pt(en)3] Cl4, K4 [Mo(CN)8], [C0{(0H)2Co(en)2}3] (NO3)6,Na6C6(C00)6, K4 [Fe(CN)6] and [Co(en)3] (C1O4)3 Ion pairing is a significant disturbing factor which hinders treatment of the data in terms of extended forms of the Debye-Huckel equation.
