11.16: Oxidation Numbers and Redox Reactions - Chemistry
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 the −2 state. The sulfate ion carries an overall charge … See more 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 See more "Sulfate" is the spelling recommended by IUPAC, but "sulphate" was traditionally used in British English. 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: • 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 bonding in terms of electron octets around each atom, that is no double bonds and a formal charge of +2 on the sulfur atom. See more There are numerous examples of ionic sulfates, many of which are highly soluble in water. Exceptions include calcium sulfate, 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 WebSep 21, 2024 · In recent years, advanced oxidation process (AOPs) based on sulfate radical (SO4 −) and singlet oxygen (1O2) has attracted a lot of attention because of its characteristics of rapid reaction, efficient treatment, safety and stability, and easy operation. SO4 − and 1O2 mainly comes from the activation reaction of peroxymonosulfate (PMS) … green clay man cartoon

WebApr 27, 2013 · Ben Norris' answer is excellent. I'll collaborate with a more visual procedure, so it may provide a different point of view. The way I've learned it, oxidation numbers can be determined by figuring out where the bonding electrons would be assuming bonds are 100% ionic, while formal charges can be determined by figuring out where the electrons … WebMar 26, 2010 · The proposed mechanism of enzymatic oxidation of (bi)sulfite to • SO 3 − by the active Cu(II) site of Cu,Zn-SOD proceeds in a one-electron reduction reaction of Cu(II) by (bi)sulfite, similar to the oxidation of (bi)sulfite by HRP and prostaglandin H synthase (Mottley and Mason 1988; Mottley 1982a, 1982b; Roman and Dunford 1973).
