| Abstract: | Heats of solution of acetonitrile, solvated or hydrated perchlorates, Mn(ClO4)2·6AN, Co(ClO4)2·6AN, Ni(ClO4)2·6AN, Cu(ClO4)2·4AN, Cu(ClO4)2·6H2O, Zn(ClO4)2·6AN, and Zn(ClO4)2·6H2O have been determined in NMF, DMF, DMA, and water. Complete or almost complete exchange of AN and water molecules in amides is inferred from the visible spectra determinations. The heats of transfer of perchlorate anion from water to DMA and NMF have been obtained from separately determined heats of solution of NaBPh4, AsPH4Cl·H2O, NaClO4, NaCl, and SiPh4 in the respective solvents. The heats of transfer of cations from water to amides have been determined from the above data and the heats of solvation of cations using literature data for the heats of hydration. |
