Infobox references. Sodium carbonate (also known as washing soda, soda ash and soda crystals) is the inorganic compound with the formula Na2CO3 and its various hydrates. All forms are white, odourless, water-soluble salts that yield alkaline solutions in water. Historically, it was extracted from the ashes of plants grown in sodium-rich soils ...
Sodium percarbonate or sodium carbonate peroxide is a chemical substance with formula Na2H3CO6. It is an adduct of sodium carbonate ("soda ash" or "washing soda") and hydrogen peroxide (that is, a perhydrate) whose formula is more properly written as 2 Na2CO3 · 3 H2O2. It is a colorless, crystalline, hygroscopic and water-soluble solid. [3]
Sodium bicarbonate (IUPAC name: sodium hydrogencarbonate[9]), commonly known as baking soda or bicarbonate of soda, is a chemical compound with the formula NaHCO3. It is a salt composed of a sodium cation (Na +) and a bicarbonate anion (HCO 3−). Sodium bicarbonate is a white solid that is crystalline but often appears as a fine powder.
Infobox references. A carbonate is a salt of carbonic acid, H2CO3, [2] characterized by the presence of the carbonate ion, a polyatomic ion with the formula CO2− 3. The word "carbonate" may also refer to a carbonate ester, an organic compound containing the carbonate group O=C (−O−)2. The term is also used as a verb, to describe ...
The chemical abbreviation for sodium was first published in 1814 by Jöns Jakob Berzelius in his system of atomic symbols, [45] [46] and is an abbreviation of the element's Neo-Latin name natrium, which refers to the Egyptian natron, [41] a natural mineral salt mainly consisting of hydrated sodium carbonate. Natron historically had several ...
In inorganic chemistry, bicarbonate (IUPAC -recommended nomenclature: hydrogencarbonate[2]) is an intermediate form in the deprotonation of carbonic acid. It is a polyatomic anion with the chemical formula H C O −. 3. Bicarbonate serves a crucial biochemical role in the physiological pH buffering system. [3]
Natron is a naturally occurring mixture of sodium carbonate decahydrate (Na 2 CO 3 ·10H 2 O, a kind of soda ash) and around 17% sodium bicarbonate (also called baking soda, NaHCO 3) along with small quantities of sodium chloride and sodium sulfate. Natron is white to colourless when pure, varying to gray or yellow with impurities.
Trona (trisodium hydrogendicarbonate dihydrate, also sodium sesquicarbonate dihydrate, Na 2 CO 3 ·NaHCO 3 ·2H 2 O) is a non- marine evaporite mineral. [4][6] It is mined as the primary source of sodium carbonate in the United States, where it has replaced the Solvay process used in most of the rest of the world for sodium carbonate production.
