Ammonium sulfite can be prepared by the reaction of ammonia with sulfur dioxide in aqueous solution: 2 NH3 + SO2 + H2O → (NH4)2SO3. Ammonium sulfite is produced in gas scrubbers, now obsolete, consisting of ammonium hydroxide to remove sulfur dioxide from emissions from power plants. The conversion is the basis of the Walther Process.
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 ...
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.
Ammonium sulfate is made by treating ammonia with sulfuric acid: 2 NH3 + H2SO4 → (NH4)2SO4. A mixture of ammonia gas and water vapor is introduced into a reactor that contains a saturated solution of ammonium sulfate and about 2% to 4% of free sulfuric acid at 60 °C. Concentrated sulfuric acid is added to keep the solution acidic, and to ...
Infobox references. Ammonium is a modified form of ammonia that has an extra hydrogen atom. It is a positively charged (cationic) molecular ion with the chemical formula NH+ 4 or [NH4]+. It is formed by the addition of a proton (a hydrogen nucleus) to ammonia (NH3).
Ammonium selenide [1] [NH4+]. [NH4+]. [Se-2] Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Ammonium selenide is a chemical compound with the symbol (NH 4) 2 Se. It is claimed to be a white solid and there is little to no spectroscopic evidence on this compound. [1][2]
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to ...
Lenthionine is an organic polysulfide found in shiitake mushrooms. In commerce, the term "polysulfide" usually refers to a class of polymers with alternating chains of several sulfur atoms and hydrocarbons. They have the formula R1SnR2. In this formula n indicates the number of sulfur atoms (or "rank"). Polysulfide polymers can be synthesized ...
