Overview of Potassium Bisulfate

Potassium Bisulfate (KHSO₄) is an inorganic chemical compound used primarily as a mild acidulant in various industrial applications. It is a white, crystalline solid that is highly soluble in water. Potassium Bisulfate is commonly employed in fertilizer production, chemical synthesis, and as a pH adjuster in numerous industrial processes. Its acidic nature makes it effective in cleaning agents, metal pickling, and water treatment applications.

In addition to its industrial uses, Potassium Bisulfate is also a key component in the production of potassium salts and agricultural chemicals. It plays an important role in pH regulation in processes such as dyeing and food processing.

Related products available on our website include Potassium Sulfate, Potassium Hydrogen Phosphate, and Sodium Bisulfate, which are widely used in fertiliser manufacturing, chemical industries, and water treatment.
