Sodium carbonate (CAS 497-19-8), with the formula Na₂CO₃, is a sodium salt of carbonic acid. It appears as a white, odorless powder with a strong alkaline taste and exhibits high hygroscopicity. It dissolves easily in water, forming a moderately alkaline aqueous solution. Sodium carbonate has extensive applications across various industries worldwide.
One of its primary uses is in glass manufacturing, where it serves as a flux to lower the melting point of silica; nearly half of global sodium carbonate production goes to this purpose. Besides glassmaking, it functions as a strong chemical base in pulp and paper production, textile processing, drinking water treatment, and the manufacture of soaps, detergents, and drain cleaners. Additionally, sodium carbonate is employed in tissue digestion, dissolving amphoteric metals and compounds, food processing, and as an effective cleaning agent. Its versatility and effectiveness make it indispensable in many industrial and domestic applications.
