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.

The sulfides and sulfosalts mineral class has a general formula of A m X n, where A represents a metallic element (Fe, Cu, Zn, Pb, As, Sb, Mo, etc.), and X is a sulfide – an anion of sulfur (S 2-). The letters m and n are simply integers.

Formally, "sulfide" is the di anion, 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 ~1...

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.

In this lesson we will look at sulfides. The aim of the article is to define sulfides, describe some of their properties, and provide you with examples of some common sulfide minerals.

2022年8月28日 · Sulfides and related minerals vary greatly in atomic arrangement. In this book, we divide them into tetrahedral sulfides, octahedral sulfides, and other sulfides. In tetrahedral sulfides, all metal atoms are in 4-fold coordination. In octahedral sulfides, all metal atoms are in 6-fold coordination.

Sulfides are a class of chemical compounds that contain sulfur atoms bonded to one or more electropositive elements, such as metals or hydrogen. They are important in the context of chemical reactions, particularly in the classification of reaction types.

Sulfides. Sulfur analogs of ethers are called sulfides. The chemical behavior of sulfides contrasts with that of ethers in some important ways. 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.

A sulfide is a chemical compound that contains a sulfur atom bonded to one or more electropositive elements, such as a metal or hydrogen. Sulfides are an important class of compounds in the context of chemical nomenclature, as they have distinct naming conventions and play a crucial role in various chemical processes and applications.
