Thermochemical measurement of the ligand field splitting energies for hexaaquocopper (II) and hexaamminecopper (II) ions

The vacuum dehydration of copper (II) sulphate pentahydrate has been shown to pass through the transitory tryhydrate state before proceeding to the monohydrate composition. Based on this, the heat of solution data for the high-energy modification hydrates have been reinterpreted and the low-energy c...
