摘要: In order to obtain an acidity scale in room-temperature ionic liquid solutions, the protonation equilibrium of sodium p-nitrophenolate [bm(2)im][NTf(2)] and [bmpyrr][NTf(2)], at 298 K, has been studied by means spectrophotometric titration. Carboxylic acids differing both structure water solution strength have used. Data collected indicate that analyzed solutions carboxylic are less dissociated than solution. Furthermore, virtue a mutual interaction, seems be affected nature liquids acids.
