Abstract
The concentration dependences of the properties of solutions of α-NiSO4 · 6H2O (mineral retgersite) in H2O and 20% H2SO4 have been measured in a wide range of concentrations (up to ∼20 solvent molecules per dissolved-salt molecule). It is shown that the solution density, the light absorption coefficient at a wavelength of 394 nm, and the intensity of the Raman scattering peak characteristic of the sulfate ion depend linearly on the bulk salt concentration in the solutions. No shift of the Raman peak as a result of a change in the concentration was observed. These facts indicate that the type of dissolved particles and the character of interactions between them and with the solvent remain the same with an increase in the salt concentration. The data in the literature on the formation of ion pairs in retgersite solutions are discussed.
