Sulfate cation or anion
The sulfate or sulphate ion is a polyatomic anion with the empirical formula SO2−4. 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. See more "Sulfate" is the spelling recommended by IUPAC, but "sulphate" was traditionally used in British English. See more The sulfate anion consists of a central sulfur atom surrounded by four equivalent oxygen atoms in a tetrahedral arrangement. The symmetry is the same as that of methane. The sulfur atom is in the +6 oxidation state while the four oxygen atoms are each in … See more Methods of preparing metal sulfates include: • treating metal, metal hydroxide, metal carbonate or metal oxide with sulfuric acid Zn + H2SO4 → ZnSO4 + H2 Cu(OH)2 + H2SO4 → CuSO4 + 2 H2O CdCO3 + H2SO4 → CdSO4 + … See more Commercial applications Sulfates are widely used industrially. Major compounds include: • Gypsum, the natural mineral form of hydrated See more The first description of the bonding in modern terms was by Gilbert Lewis in his groundbreaking paper of 1916 where he described the … See more There are numerous examples of ionic sulfates, many of which are highly soluble in water. Exceptions include calcium sulfate, strontium sulfate, lead(II) sulfate, and See more Some sulfates were known to alchemists. The vitriol salts, from the Latin vitreolum, glassy, were so-called because they were some of the first transparent crystals known. Green vitriol is iron(II) sulfate heptahydrate, FeSO4·7H2O; blue vitriol is copper(II) … See more
