Description

Sodium Bisulfate Monohydrate is an inorganic acid salt widely recognized for its versatility as a pH adjuster, acidulant, and cleaning agent. Its commercial importance stems from its strong acidic nature in solution, providing a cost-effective and efficient alternative to sulfuric acid for many applications. This product is essential for manufacturers and processors in the water treatment, metal finishing, food processing, and cleaning product industries.

Application

• pH Control & Water Treatment: Used for pH reduction and alkalinity control in swimming pools, industrial wastewater treatment, and boiler feed water systems.
• Metal Surface Treatment: Employed in pickling and cleaning baths to remove rust, scale, and oxides from steel and other metal surfaces prior to plating or coating.
• Industrial Cleaning: A key acidic component in commercial and industrial cleaners for descaling, toilet bowl cleaners, and metal cleaning formulations.
• Food Processing: Utilized as an acidulant (food additive E514) for pH adjustment, leavening agent in baked goods, and as a cleaning/sanitizing agent for food processing equipment.
• Chemical Manufacturing: Serves as a raw material or catalyst in various chemical synthesis processes and as a source of bisulfate ions.
• Dyeing & Textile Processing: Acts as an acidifying agent in dye baths and other textile chemical processes.

Quality Control

Our Sodium Bisulfate Monohydrate is manufactured under a stringent quality management system. Each batch is tested to ensure it meets precise specifications for purity, assay, and impurity profiles. While available in technical and food-grade (FCC) qualities, all products are supported by comprehensive batch documentation. Certificates of Analysis (COA) are provided and available upon request to guarantee traceability and compliance with your requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent caking and absorption of atmospheric moisture. Store separately from strong bases and oxidizing agents.
