Conductance studies of NaCl, KCl, NaBr, KBr, NaI, Bu4NI, and NaBPh4 in water + 2-propoxyethanol mixtures at 298.15 K

Abstract

The molar conductances of sodium chloride (NaCl), potassium chloride (KCl), sodium bromide (NaBr), sodium iodide (NaI), tetrabutylammonium iodide (Bu 4 NI), and sodium tetraphenylborate (NaBPh 4 ) in water + 2-propoxyethanol binary mixtures at T=298.15 K were determined. Conductance values were analyzed using a lowconcentration chemical model (lcCM). The ionic conductivities of Na + , K + , Bu 4 N + , Cl − , I − , Br − , and BPh 4 − ions were determined using Fuoss-Hirsch's assumption. The dependencies of the values of limiting molar conductance (Λ o ), limiting ionic conductance of the individual anions (λ o ± ), and Walden products (Λ o ⋅η and λ o ± ⋅η) as a function of the composition of water+2-propoxyethanol binary mixtures were discussed.

Electrical Conductivity of Ionic Liquids 1-Hexyl-3-Methylimidazolium Chloride (HMIM) and 1-Methyl-3-Octylimidazolium Chloride (OMIM) in Mixtures with Selected Alkoxy Alcohols over a Wide Temperature Range

“…The experimental procedure for conductometric measurements is detailed in the references [52][53][54]. Electrical conductivity measurements were conducted using an RLC Wayne-Kerr 6430B conductometric bridge with an uncertainty of 0.02%.…”

Conductometric and Thermodynamic Studies of Selected Imidazolium Chloride Ionic Liquids in N,N-Dimethylformamide at Temperatures from 278.15 to 313.15 K

“…All solutions were prepared using an analytical balance (Sartorius RC 210D)(Goettingen, Germany) with an accuracy of ±1·10 −5 g. The measurement procedure was based on the method described by Bešter-Rogač et al [ 54 , 55 , 56 ]. Electrical conductivity measurements were performed using a three-electrode cell constructed with PYREX glass and a Precise Component Analyzer bridge type 6430B (Wayne-Kerr, West Sussex, UK).…”
