The chemical formula is Na2CO3, commonly known as soda ash, soda ash, alkali ash, disodium carbonate, and soda ash. It is usually a white powder and a strong electrolyte with a density of 2.532g/cm3 and a melting point of 851 ° C. It is easily soluble in water and glycerol, slightly soluble in anhydrous ethanol, and difficult to dissolve in propanol. It has salt like properties and belongs to inorganic salts. Moist air can absorb moisture and form lumps, some of which turn into sodium bicarbonate.
