Sodium carbonate with best price cas 497-19-8
The chemical formula of sodium carbonate is Na2CO3, which is commonly known as soda, soda,
alkali ash and washing alkali. Under ordinary circumstances, it is a white powder and a strong electrolyte.
Density of 2.532 g/cm3, melting point is 851 ° C, soluble in water, connectivity with salt,
is a kind of weak acid salt, slightly soluble in anhydrous ethanol, not soluble in propanol,
soluble in water after hydrolysis reaction, make show alkaline solution, has certain corrosion resistance,
can reacts with the acid, generate the corresponding salt and gives off carbon dioxide.
It can be decomposed at high temperature to form sodium oxide and carbon dioxide.
