The hydration, poly- and depolymerization, and redox reactions involving ruthenium(IV) and ruthenium(III) that occur in hydrochloric acid solutions upon microwave irradiation are studied by UV-visible molecular absorption spectroscopy by the example of potassium μ-oxo-bis[pentachlororuthenate(IV)] K4[Ru2OCl10]. The microwave irradiation significantly accelerates these processes, primarily, depolymerization. The contents of ruthenium(IV) and ruthenium(III) species, and the absorption characteristics of the complexes formed are calculated. Varying the microwave radiation parameters and the HCl concentration enables one to obtain solutions dominated by the species [RuCl6]2- (95%) and [(RuOH)2(H2O)6(OH)2]4+ (98%), which cannot be produced by heating in a boiling water bath. By the example of ruthenium(IV) hydration, the effect exerted on this process by the microwave radiation itself, i.e., as a nonthermal factor, is revealed.
