- Definition of H2SeO4
H2SeO4 is commonly known as Selenic acid. In English, this substance is also referred to as Selenic acid. H2SeO4 is a basic chemical compound consisting of 2 hydrogen atoms, 1 selenium atom, and 4 oxygen atoms. In this compound, the selenium atom has an atomic mass of 78.96 amu and the oxygen atom has an atomic mass of 16.00 amu.
H2SeO4 does not exist as separate ions in solution, but instead it dissociates into H+ ions and SeO4^2- ions.
