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]
Sulfuric acid ( American spelling and the preferred IUPAC name) or sulphuric acid ( Commonwealth spelling ), known in antiquity as oil of vitriol, is a mineral acid composed of the elements sulfur, oxygen, and hydrogen, with the molecular formula H2SO4. It is a colorless, odorless, and viscous liquid that is miscible with water.
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.
Hydrogen sulfide was a reagent in the qualitative inorganic analysis of metal ions. In these analyses, heavy metal (and nonmetal) ions (e.g., Pb (II), Cu (II), Hg (II), As (III)) are precipitated from solution upon exposure to H2S. The components of the resulting solid are then identified by their reactivity.
Hydrogen peroxide is a chemical compound with the formula H 2 O 2.In its pure form, it is a very pale blue [5] liquid that is slightly more viscous than water.It is used as an oxidizer, bleaching agent, and antiseptic, usually as a dilute solution (3%–6% by weight) in water for consumer use and in higher concentrations for industrial use.
Sulfur dioxide is the product of the burning of sulfur or of burning materials that contain sulfur: 1⁄8 S8 + O2 → SO2, ΔH = −297 kJ/mol. To aid combustion, liquified sulfur (140–150 °C (284–302 °F) is sprayed through an atomizing nozzle to generate fine drops of sulfur with a large surface area.
Sulfur oxoacid. Sulfur oxoacids are chemical compounds that contain sulfur, oxygen, and hydrogen. The best known and most important industrially used is sulfuric acid. Sulfur has several oxoacids; however, some of these are known only from their salts (these are shown in italics in the table below). The acids that have been characterised ...
Sulfur trioxide (alternative spelling sulphur trioxide, also known as nisso sulfan) is the chemical compound with the formula SO 3. It has been described as "unquestionably the most [economically] important sulfur oxide". [ 1] It is prepared on an industrial scale as a precursor to sulfuric acid . Sulfur trioxide exists in several forms ...
