Apparent molar volumes for dilute solutions of NaClO4 and [Co(en) 3](ClO4)3 in D2O and H2O at 278-318 K
Description
Apparent molar volumes for dilute solutions of NaClO4 and [Co(en)3](ClO4)3 in D2O and H2O were measured by using a dilatometry technique at 278, 298 and 318K. Comparison of limiting slopes with the Debye-Huckel predictions from the dielectric constant and compressibility of H2O and D2O is complicated by ion pairing. The apparent molar volumes for NaClO4 were less in D2O than in H2O. The complex [Co(en)3](ClO4)3 when studied in D2O had its amine protons exchanged by deuterium; this did not allow a direct comparison of the apparent molar volumes of the protonated complex in each solvent system, but revealed a large isotope effect. The apparent molar volumes of the [Co(en)3](ClO4)3 showed a much larger temperature dependence than that of NaClO4
