Abstract

The acid and base ionization constants of 1-(2-carbamylethyl)-2-alkylimidazoles, as well as the acid ionization constants of acrylamide and acetamide, have been determined by potentiometry. Concentration constants at 10.0, 25.0 and 40.0 degrees and I = 0.1M (KNO(3)) were measured. From plots of log K vs. 1/T the thermodynamic parameters (DeltaH and DeltaS) of the ionization reactions were calculated.
