Mercury sulfide solubility
Mercury selenide (HgSe; sometimes mercury(II) selenide) is a chemical compound of mercury and selenium. It is a grey-black crystalline solid semi-metal with a sphalerite structure. The lattice constant is 0.608 nm. HgSe occurs naturally as the mineral Tiemannite, and is a component of the "intimate mixture" of HgSe and Se known as HgSe2. Webobserved as the sulfide was added and given time to undergo reaction. As the treated solution was drawn through the elemental sulfur bed, black dis-coloration appeared in the upper portion of the bed. Purification is obtained by the sulfide reacting with the mercuric ox e species to form the black insoluble mercuric sulfide (HgS solubility = 10-4
