Description

  • General description: Selenous acid is a dibasic acid.[1] It is the oxoacid of selenium and can be formed by adding selenium dioxide gas to water. Selenous acid shows analogy to sulfurous acid. As a crystalline solid, the molecules are arranged in a pyramid and in a solution it behaves as a diprotic acid.[2]
  • Application: Selenic acid etching assisted vacancy engineering for designing highly active electrocatalysts toward the oxygen evolution reaction: Examination of the use of selenous acid in vacancy engineering for electrocatalysts (Zhang et al., 2021). Europium (III) Catalysis for Reduction of Thionine Dye by Selenous Acid in Aqueous Sulfuric Acid Solutions: Study on the kinetics and mechanism of selenium(IV) reduction in aqueous sulfuric acid solutions (Fawzy, 2016).
  • Packaging: Packaged in High-Density Polyethylene (HDPE)
