Abstract: The solubility diagrams for the Rb₂Se0₃ —H₂Se0₃ —H₂0 and Cs₂Se0₃—H₂Se0₃—H₂0 systems were studied for the first time, at 298 K. On the basis of the solubility study results, the conditions for the preparation of the acidic salts, RbHSeO₃ , RbH₃ (Se0₃)₂ , CsHSe0₃, and CsH₃(Se0₃)₂ , have been refined and the compound, CsH₅(Se0₃)₃, that has not yet been de­ scribed, has been prepared. The thermoanalytical properties and the in­ frared spectra of the compounds obtained were studied. The results have contributed to the clarification of the behaviour of the protons in the hydrogen bonds of the compounds studied. During the study of the ther­moanalytical properties, the diselenites, Rb₂Se₂0₅ and Cs₂Se₂0₅ were found that have not yet been described.
