Selenous Acid (Selenius Acid)

Product Description

Selenous Acid (H₂SeO₃), also known as Selenius Acid, is a powerful oxidizing agent and intermediate selenium compound. It appears as a colorless to slightly pink crystalline solid that dissolves easily in water to form a strongly acidic solution.
This compound is widely used in analytical chemistry, electroplating, glass manufacturing, and organic synthesis. In laboratories, Selenous Acid serves as an oxidizing reagent, precursor for selenium dioxide, and standard solution for trace element analysis.
