ABOUT THE PRODUCT

Product Description

Product Description-Sodium Carbonate CAS#497-19-8

Sodium carbonate (CAS 497-19-8, formula Na₂CO₃) is the sodium salt of carbonic acid. This white, odorless solid has a strong alkaline taste and high hygroscopicity. It dissolves readily in water to form a moderately alkaline solution, and is widely applied across various industries worldwide.

Product Applications-Sodium Carbonate CAS#497-19-8

A primary application of sodium carbonate is glass manufacturing, where it acts as a flux to reduce silica’s melting point — this use accounts for nearly half of global production. Beyond glassmaking, it serves as a strong alkaline base in pulp and paper production, textile processing, drinking water treatment, and the manufacture of soaps, detergents and drain cleaners. It is also used for tissue digestion, dissolving amphoteric metals and compounds, food processing, and as an effective cleaning agent. Its versatility and efficacy make it indispensable across numerous industrial and domestic uses.
