¹⁹⁹Hg NMR of aqueous solutions of inorganic mercury salts. Chemical shifts of HgCl^{2 − <i>n</i>} with <i>n</i> = 0–4

Abstract

Abstract 119 Hg NMR chemical shifts of the stable mercury species HgCl with n = 0–4 were determined by a least‐squares algorithm from 199 Hg chemical shifts measured in 50 mM aqueous mercury solution as a function of the chlorine concentration at 25°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 (Hg 2+ ), −1897 ppm (HgCl + ), −1560 ppm (HgCl 2 ), −1436 ppm (HgCl 3 − ) and −1152 ppm (HgCl ) with maximum errors of ±5 ppm.
