  2. Sulfite - Wikipedia

    en.wikipedia.org/wiki/Sulfite

    A space-filling model of the sulfite anion. Sulfites or sulphites are compounds that contain the sulfite ion (systematic name: sulfate(IV) ion), SO 2− 3. The sulfite ion is the conjugate base of bisulfite. Although its acid (sulfurous acid) is elusive, [1] its salts are widely used.

  3. Sulfide - Wikipedia

    en.wikipedia.org/wiki/Sulfide

    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.

  4. Sulfite sulfate - Wikipedia

    en.wikipedia.org/wiki/Sulfite_sulfate

    A sulfite sulfate is a chemical compound that contains both sulfite and sulfate anions [SO 3] 2− [SO 4] 2−. These compounds were discovered in the 1980s as calcium and rare earth element salts. Minerals in this class were later discovered. Minerals may have sulfite as an essential component, or have it substituted for another anion as in ...

  5. Sulfate - Wikipedia

    en.wikipedia.org/wiki/Sulfate

    The sulfate or sulphate ion is a polyatomic anion with the empirical formula SO 2− 4. Salts, acid derivatives, and peroxides of sulfate are widely used in industry. Sulfates occur widely in everyday life. Sulfates are salts of sulfuric acid and many are prepared from that acid.

  6. Sulfide mineral - Wikipedia

    en.wikipedia.org/wiki/Sulfide_mineral

    Some sulfide minerals are economically important as metal ores. The sulphide class also includes the selenides, the tellurides, the arsenides, the antimonides, the bismuthinides, the sulpharsenides and the sulphosalts. [1] [2] Sulphide minerals are inorganic compounds. Pyrite

  7. Calcium sulfite - Wikipedia

    en.wikipedia.org/wiki/Calcium_sulfite

    Calcium sulfite, or calcium sulphite, is a chemical compound, the calcium salt of sulfite with the formula CaSO 3 ·x(H 2 O). Two crystalline forms are known, the hemihydrate and the tetrahydrate, respectively CaSO 3 ·½(H 2 O) and CaSO 3 ·4(H 2 O). [2] All forms are white solids. It is most notable as the product of flue-gas desulfurization.

  8. Bisulfide - Wikipedia

    en.wikipedia.org/wiki/Bisulfide

    Some compounds described as salts of the sulfide dianion contain primarily hydrosulfide. For example, the hydrated form of sodium sulfide, nominally with the formula Na 2 S · 9 H 2 O, is better described as NaSH · NaOH · 8 H 2 O. The UV–visible spectrum of septic sewage from three different sites.

  9. Polysulfide - Wikipedia

    en.wikipedia.org/wiki/Polysulfide

    The alkali metal polysulfides arise by treatment of a solution of the sulfide with elemental sulfur, e.g. sodium sulfide to sodium polysulfide: S 2− + n S → S 2− n+1. In some cases, these anions have been obtained as organic salts, which are soluble in organic solvents. [4]
