Accuracy of Several Immiscible Displacement Liquids1

  1. J. A. Kittrick2

Abstract

Abstract

Equilibrium solutions were displaced from moist samples of gibbsite and calcite of known stability using four different immiscible liquids, carbon tetrachloride, tetrachloroethylene, FC70 (a fluorocarbon), and 1,1,1-trichloroethane. All four immiscible liquids permitted accurate solution analyses for gibbsite in the pH range near 4. In the pH range near 8.3, 1,1,1-trichloroethane significantly decreased the pH of solutions displaced from calcite. All solutions in this pH range required protection from CO2 variations. Tetrachloroethylene and FC70 permitted accurate analyses of displaced solutions and are less toxic than CCl4.
