Ph. Eur. 6.2

(Sodium Carbonate Monohydrate). A white or almost white, crystalline powder or colourless crystals. Freely soluble in water; practically insoluble in alcohol. A 10% solution in water is strongly alkaline. Store in airtight containers.


(Sodium Carbonate). Colourless crystals, or white, crystalline powder or granules. When exposed to dry air above 50°, it effloresces and at 100° it becomes anhydrous. Soluble 1 in 3 of water and 1 in 1.8 of boiling water.

💊 Profile

Sodium carbonate is used in antacid preparations. Anhydrous sodium carbonate and the monohydrate are also used as reagents. The decahydrate has been used in alkaline baths. Sodium carbonate in its anhydrous or hydrated form is also used as a water softener. Sodium carbonate may be irritating or mildly corrosive to skin, mucous membranes, and eyes.
