Mercury sulfide. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). ?) 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.
Cinnabar (/ ˈsɪnəˌbɑːr /; from Ancient Greek κιννάβαρι (kinnábari)), [7] or cinnabarite (/ ˌsɪnəˈbɑːraɪt /), also known as mercurblende is the bright scarlet to brick-red form of mercury (II) sulfide (HgS). It is the most common source ore for refining elemental mercury and is the historic source for the brilliant red or ...
Mercury(I) sulfide or mercurous sulfide is a hypothetical chemical compound of mercury and sulfur, with elemental formula Hg 2 S.Its existence has been disputed; it may be stable below 0 °C or in suitable environments, but is unstable at room temperature, decomposing into metallic mercury and mercury(II) sulfide (mercuric sulfide, cinnabar).
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to ...
Hydroxides of mercury are poorly characterized, as attempted isolation studies of mercury(II) hydroxide have yielded mercury oxide instead. [58] Being a soft metal, mercury forms very stable derivatives with the heavier chalcogens. Preeminent is mercury(II) sulfide, HgS, which occurs in nature as the ore cinnabar and is the brilliant pigment ...

Mercury polycations are polyatomic cations that contain only mercury atoms. The best known example is the Hg2+. 2 ion, found in mercury (I) (mercurous) compounds. The existence of the metal–metal bond in Hg (I) compounds was established using X-ray studies in 1927 [2][page needed] and Raman spectroscopy in 1934 [3] making it one of the ...
Vermilion (sometimes vermillion) [1] is a color family and pigment most often used between antiquity and the 19th century from the powdered mineral cinnabar (a form of mercury sulfide). It is synonymous with red orange, which often takes a modern form, but is 11% brighter (at full brightness).
