WebHgS is soluble only in aqua regia, which can be used to separate it from the rest. The action of ammonia is also useful in differentiating the cations. ... After separation, the easiest way to distinguish between these ions is by testing flame colour: barium gives a yellow-green flame, calcium gives brick red, and strontium, crimson red.

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 less … 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 α-HgS to black β-HgS. However β … See more β-HgS precipitates as a black solid when Hg(II) salts are treated with H2S.

WebNov 20, 2013 · As the size of the cation increases, upon moving down in the periodic table, the overlap between the orbitals decreases and the band gap shifts to lower energy. Since, the band gap decreases from ZnS to HgS, the colour of ZnS is white, CdS is yellow and HgS is black.
