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 water is made out of dissolved minerals that contain sulfate. These include baryte (BaSO 4), epsomite (MgSO 4 7H 2 O) and gypsum (CaSO 4 2H 2 0). [1] It is reported that a notable change in taste to the water is found dependent upon the type of sulfate affecting the water.
Dilute sulfuric acid is a constituent of acid rain, which is formed by atmospheric oxidation of sulfur dioxide in the presence of water – i.e. oxidation of sulfurous acid. When sulfur-containing fuels such as coal or oil are burned, sulfur dioxide is the main byproduct (besides the chief products carbon oxides and water).
Acetic acid is said to be a differentiating solvent for the three acids, while water is not. [6]: (p. 217) An important example of a solvent which is more basic than water is dimethyl sulfoxide, DMSO, (). A compound which is a weak acid in water may become a strong acid in DMSO.
Concentrated sulfuric acid is a strong dehydrating agent that can strip available water molecules and water components from sugar and organic tissue. [141] The burning of coal and/or petroleum by industry and power plants generates sulfur dioxide (SO 2) that reacts with atmospheric water and oxygen to produce sulfurous acid (H 2 SO 3). [142]
The trucks were carrying about 25,000 liters of pesticides and 76 tons of sulfuric acid, according to the National Agency for Water and Basic Sanitation, raising concerns about environmental damage.
Treatment of sulfur with hydrogen gives hydrogen sulfide.When dissolved in water, hydrogen sulfide is mildly acidic: [5] H 2 S ⇌ HS − + H +. Hydrogen sulfide gas and the hydrosulfide anion are extremely toxic to mammals, due to their inhibition of the oxygen-carrying capacity of hemoglobin and certain cytochromes in a manner analogous to cyanide and azide.
