Sodium carbonate, or soda ash, is a white, hygroscopic powder or granules with formula Na2CO3 and molecular weight 105.99 g/mol. Density 2.54 g/cm³ (anhydrous), melting point 851°C, decomposes before boiling. Soluble in water (215 g/L at 20°C), forming alkaline solutions pH 11-12; insoluble in organics. Absorbs moisture and CO2 from air. Exists as anhydrous, monohydrate, or decahydrate; produced via Solvay process from NaCl and limestone.
