Аннотация
The Pourbaix diagrams of the Cu–H2SO4–H2O and Co–H2SO4–H2O systems have been refined and the stability regions of sulfite phases in the diagrams have been identified. Phase diagrams of copper(I) copper( II) and copper(I) cobalt(II) double sulfites have been mapped out. The double sulfites Cu2SO3 · СuSO3 and Cu2SO3 · СoSO3 have been isolated from an aqueous solution saturated with sulfur dioxide. We have obtained electron paramagnetic resonance spectra of the double sulfite Cu2SO3 · СoSO3 and characterized it by X-ray diffraction, IR spectroscopy, particle size analysis, and thermogravimetry. A foundation has been laid for the thermodynamic prediction of the synthesis of the Cu2SO3 · MSO3 (M = Cu, Co) double sulfites.
