The properties of large (~100 nm) aggregates, that is, solvate associates formed in aqueous solutions of perchloric acid, including their stability in time, dependence of their structure on the solution composition and preparation procedure, and effects of temperature and mechanical impacts were studied by light scattering methods. The slow supramolecular structuring in aqueous solutions of perchloric acid was compared with the previously studied structuring in aqueous solutions of nitric acid. A number of regularities and features that can significantly affect the chemical processes in these solutions were revealed.
