The mutual consistency and reliability of the published thermodynamic quantities Δfcr, Δfaq, solubility ms, mean activity coefficient γs and water activity aw,s of the saturated solutions of alkali metal nitrites and selected bi-univalent compounds of Ni, Co, Zn, Cd, Pb, Cu, Mn and U at 25 °C have been checked and the obtained results discussed. The method has also been used for the calculation of lacking data ΔfG°cr of the following substances at 25 °C: CsNO2, Ni(NO3)2·6H2O, CoBr2·6H2O, CoI2·6H2O, Pb(ClO4)2·3H2O, Cu(NO3)2·6H2O and Pb(NO3)2.
