H2SO3as
H2SO3as is a proposed, but not established, chemical species. It would nominally consist of hydrogen, sulfur, oxygen and arsenic in the empirical formula H2SO3As. No peer-reviewed reports confirm its existence or characterize its properties. The name situates it among oxo- and oxo-arsenic acids, but it should not be conflated with known species such as sulfurous acid H2SO3 or arsenous acid H3AsO3.
Composition and possible valence: The formula could describe a neutral molecule containing a sulfur-centered oxoacidity with
Synthesis and stability: The compound has not been synthesized or isolated in standard conditions. Hypothetical preparation
Properties and reactivity: In the absence of data, predicted properties are uncertain. It would be expected
Significance and see also: H2SO3as is primarily of theoretical interest for considerations of heteroatom substitution in
