Sulfuric (IV) acid (United Kingdom spelling: sulphuric (IV) acid), also known as sulfurous (UK: sulphurous) acid and thionic acid, [citation needed] is the chemical compound with the formula H2SO3. Raman spectra of solutions of sulfur dioxide in water show only signals due to the SO2 molecule and the bisulfite ion, HSO− 3. [2] .

Sulfurous acid appears as a colorless liquid with a pungent burning sulfur odor. Corrosive to metals and tissue. Sulfurous acid is a sulfur oxoacid. It is a conjugate acid of a hydrogensulfite. It is a tautomer of a sulfonic acid. NA has been reported in Homo sapiens, Trypanosoma brucei, and Terminalia chebula with data available.

Aug 12, 2022 · Formula for naming oxyanions with -ite ending: Base name of oxyanion and -ous + acid. Example: H2SO3 is sulfurous acid. b. Oxyanions with -ate ending. The name of the acid is the root of the anion followed by the suffix -ic.

Molar mass calculator computes molar mass, molecular weight and elemental composition of any given compound.

Sulfurous Acid is a chemical compound which has a formula H 2 SO 3, and is a weak and unstable acid, formed when sulfur dioxide dissolves in water. The facts that sulfur dioxide actually exists in solution, cannot be said surely, but the molecules of this substance has been detected in the gas phase. It is a reducing, as well as a bleaching agent.

H2SO3 is chemically known as Sulfurous Acid. Sulfurous acid is also referred to as Sulfur dioxide solution or trioxosulfuric acid or di-hydrogen trioxosulfate. It is an intermediate species that forms acid rain from sulfur dioxide (which is SO2).

May 7, 2015 · The ion corresponding to protonated sulfurous acid, H3SO3(+), has been successfully delivered into the gas phase by electrospray ionization of the solution of a suitable precursor and an in-source fragmentation process. The neutral acid is a highly elusive molecule.
