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. Meer weergeven 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 Meer weergeven 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 α-HgS to black β-HgS. … Meer weergeven 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 … Meer weergeven • Mercury poisoning • Mercury(I) sulfide (mercurous sulfide), Hg 2S Meer weergeven WebMercury(II) sulfide is a red or black solid.
