- 中文摘要: The conductance of NaClO/sub 4/ at (25-45).degree. C in methanol-H/sub 2/O, and glycerol-H/sub 2/O mixtures in a concentration range up to 10/sup -2/M has been measured. The association constant, K/sub A/, values have been determined, where the conductometric data were analysed by a M S X computer using the Fuoss-Aprano method. The K/sub A / values for NaClO/sub 4/ in methanol-H/sub 2/O are higher than in glycereol-H/sub 2/O mixtures, Also K/sub A/ values increase as the proportional of methanol or glycerol increases in mixture. The thermodynamic parameters .DELTA.H/sup 0/,.DELTA.G/sup 0/, and .DELTA.S/sup 0/ were also calculated. It is obvious that the entire process of the ionic association in those systems are endothermic ones. The Walden products,.LAMBDA./sub 0/.eta., were calculated for all systems investigated.
