Description

Sodium Carbonate, Monohydrate is the monohydrate crystalline form of sodium carbonate, a fundamental inorganic salt with the CAS registry number 5968-11-6. This compound is valued for its consistent alkalinity and controlled reactivity, making it a reliable reagent and processing aid across multiple industries. It is essential for manufacturers and laboratories requiring a stable, solid source of carbonate ions with predictable water content.

Application

• Chemical Synthesis & Manufacturing: Acts as a pH buffer, precipitating agent, and source of carbonate ions in various inorganic and organic synthesis processes.
• Water Treatment: Used for pH adjustment and water softening in industrial boiler feed water and municipal treatment facilities.
• Detergent & Cleaning Formulations: Serves as a builder and alkalinity source in powdered industrial and institutional cleaning products.
• Laboratory Reagent: Employed as a standardizing agent in analytical chemistry and as a primary standard in titrations.
• Glass Manufacturing: Functions as a fluxing agent to lower the melting point of silica in the production of certain types of glass.
• Textile Processing: Utilized in scouring and dyeing baths to control pH and assist in the removal of impurities from fibers.
• Food Processing (where compliant): May be used as an acidity regulator, raising agent, or stabilizer in specific food-grade applications under appropriate regulatory approvals.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept in its original, sealed packaging until use to prevent caking and degradation due to atmospheric moisture.
