What is a sulfide anion?
Sulfide is an inorganic anion of sulfur with the chemical formula S2− or a compound containing one or more S2− ions. It contributes no color to sulfide salts.
What does the word sulfide mean?
sulfur
Definition of sulfide 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.
How do you identify sulphides?
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. They often are strikingly coloured and have a low hardness and a high specific gravity.
What are metal sulphides?
Metal sulfides are a major group of minerals that provide the crystal chemist a rich field for investigation due to their diverse structural types. They are abundant and cheap since they usually exist in nature as minerals such as heazlewoodite (Ni3S2), chalcocite (Cu2S), pyrite (FeS2) and so on.
What is sulphide used for?
Sodium sulfide (Na2S) is an important industrial chemical, used in manufacture of kraft paper, dyes, leather tanning, crude petroleum processing, treatment of heavy metal pollution, and others.
How is sulfide formed?
sulfide, also spelled sulphide, any of three classes of chemical compounds containing the element sulfur. Phosphine sulfides are formed from the reaction of organic phosphines with sulfur, in which the sulfur atom is linked to the phosphorus by a bond that has both covalent and ionic properties.
Is hydrogen a sulphide gas?
Hydrogen sulfide (also known as H2S, sewer gas, swamp gas, stink damp, and sour damp) is a colorless gas known for its pungent “rotten egg” odor at low concentrations. It is extremely flammable and highly toxic. Hydrogen sulfide also occurs naturally in sewers, manure pits, well water, oil and gas wells, and volcanoes.
What is the difference between sulfide and sulfate?
As nouns the difference between sulfide and sulfate is that sulfide is (chemistry) any compound of sulfur and a metal or other electropositive element or group while sulfate is (organic chemistry) any ester of sulfuric acid.
What is difference between sulphide and sulfide?
sulfide, also spelled sulphide, 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.
Where is sulfide found?
Hydrogen sulfide is found naturally in crude petroleum and natural gas. It is also produced through the bacterial breakdown of organic matter. Hydrogen sulfide can be produced by decomposing human and animal waste, and is found in sewage treatment plants and livestock areas.
What is the name of the anion with the Formula 2-?
Sulfide (2-) is a divalent inorganic anion obtained by removal of both protons from hydrogen sulfide. It is a conjugate base of a hydrosulfide. Chemical groups containing the covalent sulfur bonds -S-. The sulfur atom can be bound to inorganic or organic moieties.
What are the characteristics of sulfides?
Minus a few exceptions, most sulfides are opaque, dense, and produce a dark streak. Due to their tendency to bind with metals, sulfides are economically valuable as most metal ores processed to obtain lead, copper, and silver contain sulfides.
What is the molecular weight of 2-sulfide?
Molecular Weight. 32.07 g/mol. Date s. Modify. 2021-04-17. Create. 2004-09-16. Sulfide (2-) is a divalent inorganic anion obtained by removal of both protons from hydrogen sulfide. It is a conjugate base of a hydrosulfide.
What is the oxidation state of sulfide 2-?
Sulfide(2-) is a divalent inorganic anion obtained by removal of both protons from hydrogen sulfide. It is a conjugate base of a hydrosulfide. A sulfide or sulphide (UK) is an anion of sulfur in its lowest oxidation state of 2-.
