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.

2023年8月29日 · 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 ...

2018年6月11日 · 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.

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.

2018年3月13日 · Sulfide. A sulfide ion is composed of a lone sulfur atom. Its charge is negative two, giving sulfides this formula: S^2-. Sulfide ions are extremely basic. One well-known ionic compound with a sulfide ion is H_2S. The infamous rotten-egg smell often associated with sulfur originates from this compound. Sulfide compounds are fairly soluble.

2024年4月12日 · Sulphide , also known as sulfide, is the inorganic anion of sulfur. It's a compound that features one or more S 2− ions. The chemical formula for sulphide is also S 2− . Many elements, including sulphides, are typically found naturally in the form of minerals.
