Description
Microscopic structures in aqueous alcohol and aqueous acid solutions were studied through mass spectrometric analyses of clusters generated by the fragmentation of liquid droplets. For water-alcohol binary mixtures, the self-association of alcohol molecules was found to be related to their physicochemical properties, such as the viscosity, phase separation and preferential solvation. The molecular self-association of alcohol induced by the coexistence of water was explained by the relativity of the intermolecular interaction energies led by the mixing of water with alcohol. For aqueous acid solutions, cluster structures in aqueous nitric acid, sulfuric acid and acetic acid solutions were found to reflect their acidity in water, that is, the ionization efficiency. Furthermore, the neutralization of acetic acid by sodium hydroxide to form sodium acetate was observed as a change of the cluster-level structure.
