Supramolecular structuring of aqueous solutions of strong acids: manifestations in light scattering, NMR, and oxidation kinetics. Does liquid have a drop-like nature? 1. Nitric acid

The properties of large (~100 nm), supramolecular assemblies in aqueous solutions of nitric acid were studied by light scattering methods. The dependence of structural characteristics on the solution composition, stability in time, and effects of temperature and mechanical impacts were determined. The previously obtained data on the structure of the reaction medium and kinetics of acetone oxidation in aqueous solutions of nitric acid were used in the discussion. The identified trends and features confirm the role of supramolecular structuring in the kinetic anomalies involved in acetone oxidation.
