    Sodium Carbonate CAS 497-19-8

    Sodium Carbonate, commonly referred to as Soda Ash (Light & Dense), is an inorganic industrial ingredient widely used in base-forming and alkalinity-control processes. It functions through carbonate ion dissociation, providing pH regulation and flux behavior in high-temperature or aqueous industrial systems. Sodium Carbonate (CAS 497-19-8) is typically applied in glass manufacturing process, where it serves as a key raw component to lower melting temperature and support controlled silicate formation.
    For industrial operations, this material is supplied with competitive factory pricing, customized specifications, complete documentation including MSDS, TDS, COA, and support for bulk supply across continuous production environments.

    Physicochemical properties

    PropertyValue
    CAS Number497-19-8
    Molecular FormulaNa₂CO₃
    Molecular Weight105.99 g/mol
    AppearanceWhite powder or fine granules (anhydrous pure product)
    Density2.53 g/cm³
    Melting Point851 °C (lit.)
    Boiling Point1600 °C
    Refractive Index1.535
    Solubility– Soluble in water (22 g/100 mL at 20 °C)
    – Slightly soluble in anhydrous ethanol
    – Insoluble in acetone
    pHAqueous solutions are strongly alkaline. For example, the pH of 1%, 5%, and 10% sodium carbonate solutions at 25 °C are 11.37, 11.58, and 11.70, respectively.
    Stability– In air, it readily deliquesces and absorbs CO₂ to form sodium bicarbonate.
    – Decomposes at high temperatures (>400 °C) to produce sodium oxide and carbon dioxide.

    Application Areas

    Industrial manufacturing: Used in the glass industry to lower the melting point of silica, improve glass transparency, and produce chemical raw materials such as detergents, silicates, and phosphates
    Environmental governance: Neutralizing acidified lakes and soils, restoring ecosystems
    Laboratory use: As an acid-base titration reagent, used for analytical chemistry and water treatment softeners

    Storage conditions

    Environmental requirements: A cool, dry, and well ventilated place to avoid moisture or high temperatures
    Packaging: Plastic woven bag lined with polyethylene (40kg/bag) or sealed container
    Taboo: It is strictly prohibited to store mixed with acids, ammonium salts, and flammable materials

    Safety precautions

    Operation protection: Avoid inhaling dust, it is recommended to wear dust masks and goggles
    Leakage treatment: Absorb with inert materials and dispose of according to environmental regulations to prevent water pollution
    Skin contact: Immediately rinse with clean water for at least 15 minutes

    FAQ - Technical & Supply Chain

    • Q:

      Do Soda Ash Light and Soda Ash Dense correspond to the same CAS number?

      A: Yes. Soda Ash Light and Soda Ash Dense represent different physical forms of sodium carbonate but correspond to the same chemical substance and the same CAS number.
    • Q:

      Is Sodium Carbonate primarily intended for industrial processing rather than laboratory use?

      A: Sodium Carbonate is commonly used as an industrial ingredient in large-scale processes such as glass manufacturing, where it functions as part of controlled formulation and production systems.
