摘要：
The conductances of aqueous solutions of the above-mentioned compounds have been measured in the range of ionic strength between 5 x 10(-4) - 10(-2) at 25 degrees C. The decrease in equivalent conductance due to the increase in concentration always becomes smaller with increasing molecular weight of the tetraalkylammonium ions. K4Fe(CN)(6) is comparable to (Me4N)(4)Fe(CN)(6), K4Mo(CN) s is intermediate between the tetraethyl- and the tetra-n-propylammonium salts, and K3Co(CN)(6) has a conductance larger than the tetra-n-butylammonium salt. These results are compared with the kinetic salt effects due to the tetraalkylammonium ions.
