General description
Selenous acid is a dibasic acid. 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.
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).
