A number of processes have been designed to remove hydrogen sulfide from drinking water. [54] Continuous chlorination For levels up to 75 mg/L chlorine is used in the purification process as an oxidizing chemical to react with hydrogen sulfide. This reaction yields insoluble solid sulfur. Usually the chlorine used is in the form of sodium ...
Sodium hydrosulfide is the chemical compound with the formula NaSH. This compound is the product of the half-neutralization of hydrogen sulfide (H 2 S) with sodium hydroxide (NaOH). NaSH and sodium sulfide are used industrially, often for similar purposes. Solid NaSH is colorless.
Upon treatment with an acid, sulfide salts convert to hydrogen sulfide: S 2− + H + → SH − SH − + H + → H 2 S. Oxidation of sulfide is a complicated process. Depending on the conditions, the oxidation can produce elemental sulfur, polysulfides, polythionates, sulfite, or sulfate. Metal sulfides react with halogens, forming sulfur and ...
Sodium sulfide is a chemical compound with the formula Na 2 S, or more commonly its hydrate Na 2 S·9H 2 O.Both the anhydrous and the hydrated salts in pure crystalline form are colorless solids, although technical grades of sodium sulfide are generally yellow to brick red owing to the presence of polysulfides and commonly supplied as a crystalline mass, in flake form, or as a fused solid.
The structure of hydrogen disulfide is similar to that of hydrogen peroxide, with C 2 point group symmetry. Both molecules are distinctly nonplanar. The dihedral angle between the H a −S−S and S−S−H b planes is 90.6°, compared with 111.5° in H 2 O 2. The H−S−S bond angle is 92°, close to 90° for unhybridized divalent sulfur. [1]
Hydrogen sulfide chemosynthesis is a form of chemosynthesis which uses hydrogen sulfide. [1] It is common in hydrothermal vent microbial communities [ 2 ] [ 3 ] Due to the lack of light in these environments this is predominant over photosynthesis .
It is the salt derived from the ammonium cation and the hydrosulfide anion.The salt exists as colourless, water-soluble, micaceous crystals. On Earth the compound is encountered mainly as a solution, not as the solid, but [NH 4]SH ice is believed to be a substantial component of the cloud decks of the gas-giant planets Jupiter and Saturn, with sulfur produced by its photolysis responsible for ...
Thiourea (/ ˌ θ aɪ. oʊ j ʊəˈr iː. ə,-ˈ jʊər i-/) [2] [3]}} is an organosulfur compound with the formula SC(NH 2) 2 and the structure H 2 N−C(=S)−NH 2. It is structurally similar to urea (H 2 N−C(=O)−NH 2), with the oxygen atom replaced by sulfur atom (as implied by the thio-prefix). The properties of urea and thiourea differ ...
