The Electrical Resistance of the Lower Consolute System 2,6-Lutidine?Water

Abstract

The one-phase electrical resistance of the lower consolute system 2,6-lutidine-water has been measured in the reduced temperature range 2x 10-6 < 8 < 0·11. Particular attention has been given to the drift in resistance and separation temperature caused by the leaching of ' ions during long contact with glass surfaces. When correction is made for this effect, no contribution to the electrical resistance due to critical fluctuations is observed. The effect of the leaching of ions has not been taken into account in previously published studies which have observed, and attempted to characterize, a weak divergence in the electrical resistance of critical binary mixtures.
