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]
Related anions Notes Sulfuric acid: H 2 SO 4 +6 Sulfate, SO 2− 4 and hydrogen sulfate commonly known as bisulfate, HSO − 4: Best known and industrially significant. Polysulfuric acids including disulfuric acid (pyrosulfuric acid) H 2 SO 4 ·nSO 3 +6 Disulfate (commonly known as pyrosulfate), S 2 O 2− 7 and trisulfate, S 3 O 2− 10: Pure ...
The complementary base is the sulfoxylate anion SO 2− 2 which is much more stable. In between these states is the HSO − 2 ion, also somewhat stable. Sulfoxylate ions can be made by decomposing thiourea dioxide in an alkaline solution. [4] To do this, thiourea dioxide first forms an amidine-sulfinic acid tautomer, H 2 NC(=NH)SO 2 H, which ...
instead of attached to Cl − anions and the conjugate bases will be weaker than water molecules. On the other hand, if a chemical is a weak acid its conjugate base will not necessarily be strong. Consider that ethanoate, the conjugate base of ethanoic acid, has a base splitting constant (Kb) of about 5.6 × 10 −10 , making it a weak base.
Attempted isolation of the common salts of bisulfite results in dehydration of the anion with formation of metabisulfite (S 2 O 2− 5), also known as disulfite: 2 HSO − 3 ⇌ S 2 O 2− 5 + H 2 O. Because of this equilibrium, anhydrous sodium and potassium salts of bisulfite cannot be obtained.

The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
