Sulfide (also sulphide in British English) [2] is an inorganic anion of sulfur with the chemical formula S 2− or a compound containing one or more S 2− ions. Solutions of sulfide salts are corrosive. Sulfide also refers to large families of inorganic and organic compounds, e.g. lead sulfide and dimethyl sulfide.
Sulfide, any of three classes of chemical compounds containing the element sulfur. The three classes of sulfides include inorganic sulfides, organic sulfides (sometimes called thioethers), and phosphine sulfides. Learn more about sulfides in this article.
sulfide mineral, any member of a group of compounds of sulfur with one or more metals. Most of the sulfides are simple structurally, exhibit high symmetry in their crystal forms, and have many of the properties of metals, including metallic lustre and electrical conductivity.
1. : any of various organic compounds characterized by a sulfur atom attached to two carbon atoms. 2. : a binary compound (such as CuS) of sulfur usually with a more electropositive element or group : a salt of hydrogen sulfide.
Sulfides are the sulfur analogs of ethers just as thiols are the sulfur analogs of alcohols. Sulfides are named by following the same rules used for ethers, with sulfide used in place of ether for simple compounds and alkylthio used in place of alkoxy for more complex substances.
Sulfide minerals consist of one or more metals combined with sulfur; sulfarsenides contain arsenic replacing some of the sulfur. Sulfides are generally opaque and exhibit distinguishing colours and streaks.
sulfide, chemical compound containing sulfur and one other element or sulfur and a radical [1]. Sulfides may be salts or esters of hydrogen sulfide [2], H2S, or may be formed directly, e.g., by heating a metal with sulfur.
The term sulfide (sulphide in British English) refers to several types of chemical compounds containing sulfur in its lowest oxidation number of −2.
Describe the properties, preparation, and uses of sulfur. Sulfur exists in nature as elemental deposits as well as sulfides of iron, zinc, lead, and copper, and sulfates of sodium, calcium, barium, and magnesium.
Thiols and sulfides are the "sulfur equivalent" of alcohols and ethers. You can replace the oxygen atom of an alcohol with a sulfur atom to make a thiol; similarly, you can replace the oxygen atom in an ether with S to make the corresponding alkyl sulfide.
