HG-199 NMR OF AQUEOUS-SOLUTIONS OF INORGANIC MERCURY SALTS - CHEMICAL-SHIFTS OF HGCL2-N WITH N = 0-4

Hg-199 NMR chemical shifts of the stable mercury species HgCln2-n with n = 0-4 were determined by a least-squares algorithm from Hg-199 chemical shifts measured in 50 mm aqueous mercury solution as a function of the chlorine concentration at 25-degrees-C. The concentrations of the corresponding mercury species in the solutions necessary in this special procedures were calculated by using published equilibrium constants. The results relative to dimethyl-mercury are - 2256 ppm (Hg2+), - 1897 ppm (HgCl+), - 1560 ppm (HgCl2), - 1436 ppm (HgCl3-) and - 1152 ppm (HgCl42-) with maximum errors of +/- 5 ppm.
