Sodium carbonate is obtained as three hydrates and as the anhydrous salt: sodium carbonate decahydrate , Na 2 CO 3 ·10H 2 O, which readily effloresces to form the monohydrate. sodium carbonate heptahydrate (not known in mineral form), Na 2 CO 3 ·7H 2 O. sodium carbonate monohydrate (thermonatrite), Na 2 CO 3 ·H 2 O. Also known as crystal ...
American Natural Soda Ash Corporation (ANSAC) operates as the international distribution arm for three US manufacturers of natural soda ash produced from trona [1] deposits in Green River, Wyoming, the trade name for sodium carbonate Na 2 CO 3, is an essential raw material used in the manufacture of glass, detergents, and several sodium-based chemicals.

Benedict's reagent (often called Benedict's qualitative solution or Benedict's solution) is a chemical reagent and complex mixture of sodium carbonate, sodium citrate, and copper(II) sulfate pentahydrate. [1] It is often used in place of Fehling's solution to detect the presence of reducing sugars and other reducing substances. [2]
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.
6), an adduct of hydrogen peroxide and sodium carbonate ("soda ash" or "washing soda", Na 2 CO 3). Dissolved in water, it yields a solution of the two products, that combines the degreasing action of the carbonate with the bleaching action of the peroxide. Sodium perborate (Na 2 H 4 B 2 O 8).
An 1836 lithograph of tortilla production in rural Mexico Bowl of hominy (nixtamalized corn kernels). Nixtamalization (/ ˌ n ɪ ʃ t ə m ə l ɪ ˈ z eɪ ʃ ən / nish-tə-mə-lih-ZAY-shən) is a process for the preparation of maize, or other grain, in which the grain is soaked and cooked in an alkaline solution, usually limewater (but sometimes aqueous alkali metal carbonates), [1] washed ...
