First steps towards dissolution of NaSO4- by water.

Wang, X. B.; Woo, H. K.; Cwiklik, B. J. etc., Physical Chemistry Chemical Physics, 8 [36] 4294 - 4296 (2006)

NaSO4-((HO)-O-2)(n) (n = 0-4) clusters have been generated in the gas phase as model systems to simulate the first dissolution steps of sulfate salts in water; photoelectron spectroscopy and theoretical calculations indicate that the first three water molecules strongly interact with both Na+ and SO42-, forming a three-water solvation ring to start to pry apart the Na+SO42- contact ion pair.
