    Product Overview

    Potassium Bisulfate, with CAS number 7646-93-7, is a solid acidic acidic salt. It is an industrial commonly used solid strong acid, used for acid washing and scale removal, and as a catalyst for adjusting acid levels.

    1. The aqueous solution is highly acidic and belongs to an acid salt.
    2. Potassium Bisulfate is soluble in water but insoluble in ethanol.
    3. Potassium Bisulfate can decompose at high temperatures, releasing sulfur trioxide.
    4. Potassium Bisulfate is corrosive and has a strong acidity.
