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 ...
Ammonium sulfite can be prepared by the reaction of ammonia with sulfur dioxide in aqueous solution: 2 NH 3 + SO 2 + H 2 O → (NH 4) 2 SO 3. 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.
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 precipitate.
Ammonium sulfide forms yellow crystals, decomposing in water, of monoclinic system, space group P2 1 /c, cell parameters a = 0.5427 nm, b = 1.6226 nm, c = 0.9430 nm, β = 105.31°, Z = 4. [4] The compound can be stored under the mother liquor without air access. When dry, it decomposes quickly in the air. the compound emits sulfur intensively ...
Ammonium sulfate (American English and international scientific usage; ammonium sulphate in British English); (NH 4) 2 SO 4, is an inorganic salt with a number of commercial uses. The most common use is as a soil fertilizer. It contains 21% nitrogen and 24% sulfur.
All-solid-state electrolytes are furthermore divided into inorganic solid electrolyte (ISE), solid polymer electrolyte (SPE) and composite polymer electrolyte (CPE). On the other hand, a QSSE, also called gel polymer electrolyte (GPE), is a freestanding membrane that contains a certain amount of liquid component immobilized inside the solid matrix.
NaSH and sodium sulfide are used industrially, often for similar purposes. Solid NaSH is colorless. The solid has an odor of H 2 S owing to hydrolysis by atmospheric moisture. In contrast with sodium sulfide (Na 2 S), which is insoluble in organic solvents, NaSH, being a 1:1 electrolyte, is more soluble.
Addition of ammonium sulfate to concentrated aqueous solutions of nickel sulfate precipitates Ni(NH 4) 2 (SO 4) 2 ·6H 2 O. This blue-coloured solid is analogous to Mohr's salt, Fe(NH 4) 2 (SO 4) 2 ·6H 2 O. [1] Nickel sulfate has some uses in the laboratory.
