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. It consists of two hydroxy groups attached to a sulfur atom. [2] . Sulfoxylic acid contains sulfur in an oxidation state of +2.

It is a colorless gas with a pungent smell that is responsible for the odor of burnt matches. It is released naturally by volcanic activity and is produced as a by-product of copper extraction and the burning of sulfur - bearing fossil fuels. [9]

2021年12月10日 · Sulfur-containing radicals HSO 2• and HOSO • are key intermediates involved in stratospheric sulfur geoengineering by SO 2 injection. The spectroscopic characterization and photochemistry of both radicals are crucial to understanding the chemical impact of SO 2 chemistry in the stratosphere.

2025年3月28日 · Sulfuric acid is a very strong acid; in aqueous solutions it ionizes completely to form hydronium ions (H 3 O +) and hydrogen sulfate ions (HSO 4−). In dilute solutions the hydrogen sulfate ions also dissociate, forming more hydronium ions and sulfate ions (SO 42−).

2024年1月4日 · Given the oxidation state on S, it seems the correct name should be hyposulphurous acid, but I have seen multiple sources call it sulphoxylic acid, or both What is the reasoning behind this nomeculture.

The meaning of SULFOXYLIC ACID is a hypothetical acid S (OH)2 or HSO2H known in the form of various organic derivatives.
