Alternatively, sodium sulfate is or was formed in the production of lithium carbonate, chelating agents, resorcinol, ascorbic acid, silica pigments, nitric acid, and phenol. [17] Bulk sodium sulfate is usually purified via the decahydrate form, since the anhydrous form tends to attract iron compounds and organic compounds. The anhydrous form is ...

Thénardite is an anhydrous sodium sulfate mineral, Na 2 SO 4 which occurs in arid evaporite environments, specifically lakes and playas. It also occurs in dry caves and old mine workings as an efflorescence and as a crusty sublimate deposit around fumaroles. It occurs in volcanic caves on Mount Etna, Italy.
Sodium bisulfate, also known as sodium hydrogen sulfate, [a] is the sodium salt of the bisulfate anion, with the molecular formula NaHSO 4. Sodium bisulfate is an acid salt formed by partial neutralization of sulfuric acid by an equivalent of sodium base, typically in the form of either sodium hydroxide (lye) or sodium chloride (table salt).
Sodium sulfite (sodium sulphite) is the inorganic compound with the chemical formula Na 2 SO 3. A white, water-soluble solid, it is used commercially as an antioxidant and preservative. It is also suitable for the softening of lignin in the pulping and refining processes of wood and lignocellulosic materials. [1]
However, sodium carbonate is not as strongly basic as trisodium phosphate, making it less effective in demanding applications. [ citation needed ] Zeolites, which are clay based, are added to laundry detergents as water softening agents and are essentially non-polluting; however, zeolites do not dissolve and can deposit a fine, powdery residue ...
Thus, solutions of sodium dithionite cannot be stored for a long period of time. [3] Anhydrous sodium dithionite decomposes to sodium sulfate and sulfur dioxide above 90 °C in the air. In absence of air, it decomposes quickly above 150 °C to sodium sulfite, sodium thiosulfate, sulfur dioxide and trace amount of sulfur.
The main component of both products is anhydrous sodium sulfate. Contains a small amount of polyethylene glycol. Whole bowel irrigation ( WBI ) is a medical process involving the rapid administration of large volumes of an osmotically balanced macrogol solution ( GoLYTELY , CoLyte ), either orally or via a nasogastric tube , to flush out the ...
