Sodium bisulfate

CAS: 7681-38-1

Description:
A grayish crystalline powder with strong acidic properties, capable of serving as a functional alternative to sulfuric acid in various industrial processes. Exhibits excellent solubility in water and reliable reactivity, making it a versatile agent for pH adjustment, chemical conversion, and surface treatment applications.

Key Uses:
  • Chemical Processing & Solubilization. Functions as an effective reagent for converting sparingly soluble compounds into their soluble sulfate forms, facilitating extraction, purification, and analytical workflows in laboratory and industrial settings.
  • Non-Ferrous Metallurgy. Employed as a fluxing agent in metal refining and alloy production, helping to lower melting points, remove impurities, and improve the efficiency of smelting operations for copper, zinc, and other base metals.
  • Water Treatment & pH Control. Widely utilized as a reliable pH regulator in municipal and industrial water conditioning systems, ensuring optimal acidity levels for disinfection, coagulation, and corrosion prevention.
  • Food & Feed Applications. Approved as a food additive for acidity regulation and processing aid purposes. Also incorporated into animal feed formulations as a preservative and stabilizer to extend shelf life and maintain nutritional quality.
  • Household & Industrial Cleaners. Integral component in descaling agents, toilet bowl cleaners, and multi-surface formulations, where its acidic nature effectively dissolves mineral deposits, soap scum, and alkaline residues.
  • Leather & Textile Finishing. Applied in tanning, dyeing, and fabric treatment processes to adjust bath acidity, improve dye uptake, and enhance the softness, colorfastness, and overall quality of finished materials.
