Basic Description

Synonyms	Selenious acid
Specifications & Purity	≥98%
Product 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.
