We investigate two imidazolium zwitterionic salts, 1,3-dimethylimidazolium-2-carboxylate and 1-butyl-3-methylimidazolium-2-carboxylate, together with 1-butyl-3-methylimidazolium acetate using X-ray photoelectron spectroscopy. The electronic environment of each element for the two zwitterionic salts is analyzed. Due to the electron-withdrawing effect of the imidazoliumcation, the binding energies of Ccarboxyl 1s and O 1s for zwitterionic salts are higher than those of 1-butyl-3-methylimidazolium acetate. The impact of the alkyl chain length on the charge distribution is also illustrated. It suggests that the electron-withdrawing effect of the imidazoliumcation decreases along with the increasing of the alkyl chain length.
