In this work, densities of binary mixtures of {N, N-diethylformamide (DEF) + o-xylene, or + m-xylene, or + p-xylene}, have been determined under atmospheric pressure as a function of composition using a vibrating-tube densimeter. The temperatures studied were T (293.15, 303.15, 313.15, 323.15, 333.1

The activity coefficient data were reported for (water + potassium chloride + DL-valine) at T = 298.15 K and (water + sodium chloride + L-valine) at T = 308.15 K. The measurements were performed in an electrochemical cell using ion-selective electrodes. The maximum concentrations of the electrolytes
