High Quality Soda Ash Dense And Light 98% Min Sodium Carbonate Anhydrous Soda Ash Na2CO3




The chemical formula of sodium carbonate is Na2CO3, the common name is soda ash, soda and washing soda. Under normal circumstances, it is a white powder and a strong electrolyte. Sodium carbonate is a weak acid and strong base salt (soda ash is a salt, not an alkali, but the solution is strongly alkaline). Chemically produced Na2CO3 is purer than trona, so people call it "soda ash".


Soda ash has a density of 2.532g/cm3 and a melting point of 851°C. It is easily soluble in water and has the properties of a salt. It is a weak acid salt, slightly soluble in absolute ethanol, insoluble in propanol, and will be hydrolyzed after being dissolved in water. The reaction makes the solution alkaline and corrosive. It can neutralize with acid to generate corresponding salt and release carbon dioxide.
It can be decomposed at high temperature to produce sodium oxide and carbon dioxide.

Long-term exposure to the air can absorb moisture and carbon dioxide in the air, generate sodium bicarbonate, and form hard lumps.


Sodium carbonate is very hygroscopic, it is easy to form hard lumps, and does not decompose under high temperature. Sodium carbonate and water generate three hydrates: Na2CO3·10H2O, Na2CO3·7H2O, and Na2CO3·H2O. Among them, Na2CO3·Chemicalbook10H2O is the most stable and has a very small heat of dissolution in water. It is mostly used in the photographic industry, and its trade name is Carbon Oxygen. Na2CO3·10H2O is also called crystalline alkali, which is easy to weather in dry air. Previously, crystalline alkali was often used for household washing and wool washing, so it is also called "washing alkali".
