Product Specifications

Sodium Bisulfate is an inorganic compound with the chemical formula NaHSO₄ and CAS Number 7681-38-1 for the anhydrous form. It is typically supplied as a white crystalline powder or granular solid and is highly soluble in water, producing an acidic solution. The monohydrate form is also available under CAS Number 10034-88-5 and may have different physical properties.

Sodium Bisulfate is valued for its acidic properties and ability to lower the pH of aqueous solutions. Common laboratory applications include pH adjustment, acid-base titration studies, analytical chemistry procedures, chemical preparation, and research involving sulfate and hydrogen sulfate reactions. It is also used in specialised industrial applications, including metal cleaning, water treatment, swimming pool pH adjustment, and various chemical formulations.

Its water solubility and acidic characteristics make Sodium Bisulfate useful in analytical chemistry, inorganic chemistry, environmental research, and general laboratory applications. The appropriate grade, purity, and hydration form should be selected according to the requirements of the intended application.

KSFE Malaysia supplies laboratory chemicals and scientific products for research institutions, educational facilities, and general laboratory applications.

Safety Note: Sodium Bisulfate is an acidic chemical that may cause skin irritation and serious eye irritation or damage, depending on its concentration and formulation. Contact with moisture produces an acidic solution, and contact with strong bases may result in heat generation. Avoid inhaling dust and prevent direct contact with the eyes and skin. Do not mix with incompatible substances, particularly strong bases and certain reactive chemicals. Handle it in a well-ventilated area using appropriate personal protective equipment, including chemical-resistant gloves, safety goggles, and protective clothing. Store in a tightly closed, compatible container in a cool, dry place away from moisture, strong bases, and incompatible substances. Follow the supplier's safety data sheet (SDS) for proper handling, storage, and disposal.
