A general approach is proposed to analyze electrical conductivities in aqueous solutions of polybasic organic acids. Experimental conductivities are examined in the context of dissociation and hydrolysis reactions by applying the Quint-Viallard conductivity equations and the Debye-Hückel equations for activity coefficients. The proposed numerical procedure(More)
The knowledge base system ELDAR (ELectrolyte DAta Regensburg), consisting of data base, method base, rule base, and communication manager, classifies the knowledge of electrolyte solutions into factual, algorithmic, and rule knowledge. In this paper information is given on the factual knowledge of ELDAR and the mapping of facts in Codd's relational data(More)
Elektrochemie I Losungen I Transporterscheinungen Specific conductances of E t 4 N P F 6 , P r 4 N P F 6 , Bu 4 NPF 6 , L iPF 6 , K P F 6 , LiC10 4 , and K S C N in propylene carbonate were studied at high concentrations in the temperature range from + 2 5 ° C to — 4 5 ° C Data are fitted by a least-squares method to a four-parametric empirical equation,(More)
