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.

The meaning of SULFIDE is any of various organic compounds characterized by a sulfur atom attached to two carbon atoms.

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.

Formally, "sulfide" is the dianion, S 2−, which exists in strongly alkaline aqueous solutions formed from H 2 S or alkali metal salts such as Li 2 S, Na 2 S, and K 2 S. Sulfide is exceptionally basic and, with a pK a greater than 14, it does not exist in appreciable concentrations even in highly alkaline water, being undetectable at pH below ...

Since hydrogen sulfide (H 2 S) is a much stronger acid than water (by more than ten million fold), we expect, and find, thiols to be stronger acids than equivalent alcohols and phenols. Thiolate conjugate bases are easily formed, and have proven to be excellent nucleophiles in S N 2 reactions of alkyl halides and tosylates.

Aug 29, 2023 · Sulfide is a strong base, so solutions of sulfide in water are basic, due to hydrolysis. Sulfide solutions develop the characteristic rotten-egg odor of \(\ce{H2S}\) as a result of this hydrolysis. \[\ce{S2^{-}(aq) + H2O(l) <=> HS^{-}(aq) + OH^{-}(aq) } \nonumber \] with \(K_b = 8.3\) and \[\ce{H^{-}(aq) + H2O(l) <=> H2S(aq) + OH^{-}(aq ...

What is Sulfide? Sulfide ions are the chemical compounds with the empirical formula S 2- . Therefore, the compounds that contain sulfite ions are known as sulfite.

Hydrogen sulfide is a chemical compound with the formula H 2 S. It is a colorless chalcogen-hydride gas, and is toxic, corrosive, and flammable. Trace amounts in ambient atmosphere have a characteristic foul odor of rotten eggs. [11]

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.

Sulfate and sulfide are both chemical compounds that contain sulfur, but they have different chemical compositions and properties. Sulfate is a polyatomic ion composed of one sulfur atom and four oxygen atoms, with a charge of -2.
