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 ...
Chemical pulping involves dissolving lignin in order to extract the cellulose from the wood fiber. The different processes of chemical pulping include the Kraft process, which uses caustic soda and sodium sulfide and is the most common; alternatively, the use of sulfurous acid is known as the sulfite process, the neutral sulfite semichemical is treated as a third process separate from sulfite ...

Neodymium(III) carbonate is an inorganic compound, a salt, where neodymium is in the +3 oxidation state and the carbonate ion has charge -2. [1] It has a chemical formula of Nd 2 (CO 3) 3. The anhydrous form is purple-red, [2] while the octahydrate is a pink solid. [3] Both of these salts are insoluble in water. [4]
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]
Sodium oxalate: Na 2 C 2 O 4: Non-hygroscopic. Slightly reacts with magnesium, no reaction with aluminium. Yellow Sodium nitrate: NaNO 3: Also acts as oxidizer. Bright flame, used for illumination. Yellow Cryolite: Na 3 AlF 6: One of the few sodium salts that is nonhygroscopic and insoluble in water. Green Barium chloride: BaCl 2: Green Barium ...
