The Bunsen reaction is a chemical reaction that describes water, sulfur dioxide, and iodine reacting to form sulfuric acid and hydrogen iodide: . 2H 2 O + SO 2 + I 2 → H 2 SO 4 + 2HI ...
Sulfurous acid is commonly known to not exist in its free state, and due to this, it is stated in textbooks that it cannot be isolated in the water-free form. [4] However, the molecule has been detected in the gas phase in 1988 by the dissociative ionization of diethyl sulfite. [5]
Sulfur dioxide (IUPAC-recommended spelling) or sulphur dioxide (traditional Commonwealth English) is the chemical compound with the formula S O 2.It is a colorless gas with a pungent smell that is responsible for the odor of burnt matches.
Barium hydroxide is a chemical compound with the chemical formula Ba(OH) 2. The monohydrate ( x = 1), known as baryta or baryta-water, is one of the principal compounds of barium . This white granular monohydrate is the usual commercial form.
Although nearly 100% sulfuric acid solutions can be made, the subsequent loss of SO 3 at the boiling point brings the concentration to 98.3% acid. The 98.3% grade, which is more stable in storage, is the usual form of what is described as "concentrated sulfuric acid".

Sulfoxylic acid (H 2 SO 2) (also known as hyposulfurous acid or sulfur dihydroxide [1]) is an unstable oxoacid of sulfur in an intermediate oxidation state between hydrogen sulfide and dithionous acid.
Calcium sulfite, or calcium sulphite, is a chemical compound, the calcium salt of sulfite with the formula CaSO 3 ·x(H 2 O). Two crystalline forms are known, the hemihydrate and the tetrahydrate, respectively CaSO 3 ·½(H 2 O) and CaSO 3 ·4(H 2 O). [2]
