The acid dissociation constants of 2,4,6-trinitrophenol (picric acid) were determined in N,N-dimethylformamide and ethane-1,2-diol from -10 to +80-degrees-C and in two N,N-dimethylformamide + ethane-1,2-diol mixtures from +20 to +80-degrees-C using the conductometric method. The experimental conductivity data were analyzed by means of the Fuoss-Hsla equation, and the dissociation constants were fitted by the integrated Van't Hoff equation.

Abstract
The acid dissociation constants of 2,4,6-trinitrophenol (picric acid) were determined in N,N-dimethylformamide and ethane-1,2-diol from -10 to +80-degrees-C and in two N,N-dimethylformamide + ethane-1,2-diol mixtures from +20 to +80-degrees-C using the conductometric method. The experimental conductivity data were analyzed by means of the Fuoss-Hsla equation, and the dissociation constants were fitted by the integrated Van't Hoff equation.
