HgS is dimorphic with two crystal forms: red cinnabar (α-HgS, trigonal, hP6, P3221) is the form in which mercury is most commonly found in nature. Cinnabar has rhombohedral crystal system. Crystals of red are optically active. This is caused by the Hg-S helices in the structure. black metacinnabar (β-HgS) is … See more Mercury sulfide, or mercury(II) sulfide is a chemical compound composed of the chemical elements mercury and sulfur. It is represented by the chemical formula HgS. It is virtually insoluble in water. See more When α-HgS is used as a red pigment, it is known as vermilion. The tendency of vermilion to darken has been ascribed to conversion from red … See more • Mercury poisoning • Mercury(I) sulfide (mercurous sulfide), Hg 2S See more β-HgS precipitates as a black solid when Hg(II) salts are treated with H2S. The reaction is conveniently conducted with an acetic acid solution of mercuric acetate. With gentle heating of the slurry, the black polymorph converts to the red form. β-HgS is unreactive to all … See more WebNov 14, 2016 · The reported solubility product of H g S is 4 × 10 − 54. How is this possible? The minimum concentration that is possible is 1/avogadro's constant which shall be about 10 − 23 M. Hence the minimum value of solubility product for a diatomic specie like H g S would be about 10 − 46. What am I missing? solutions solubility concentration Share

WebAnother way of answering why HgS does not dissolve is to say that it has a very low solubility product (if you understand what that is). Hg (OH)2 is a weak base and it reacts with acids. For example, with HCl, it gives the salt mercuric chloride, which dissolves in water. Hg (OH)2 + 2 HCl —→ HgCl2 + 2 H2O. WebSep 13, 2024 · The solubility product of CuS, `Ag_(2)S`, HgS are `10^(-31), 10^(-44), 10^(54)` respectively.

Above this range, where HGS is required, higher-density brines may not achieve great benefits. If high density and full acid solubility are required (for instance with injection wells), then alternate HGS, such as ilmenite and manganese tetroxide, can be considered.
