Web15 aug. 2024 · B.P. 356.57º. Density 13.546 g/cm 3. Characteristics: Mercury is one of the few liquid elements. It dissolves in oxidizing acids, producing either Hg 2 + or Hg 2 2 +, depending on which reagent is in excess. The metal is also soluble in aqua regia ( a mixture of hydrochloric and nitric acids) to form HgCl 4 2 −. WebPurification is obtained by the sulfide reacting with the mercuric ox e species to form the black insoluble mercuric sulfide (HgS solubility = 10-4 ppm Hg; HgO solubility = 60 ppm Hg): SH+S-- HgS i + 20H K = 1026 (10) Because of the large equilibrium constant for the above reaction, much higher degrees of purity would be expected.
