p-toluenesulfonic acid sodium list of water

Sulfonic Acid

Sulfonic acids R-S(O) 2 OH (R = alkyl or aryl) are strong acids and very soluble in water. Sulfuric acid forms both mono and diesters, aikylsulfuric acids RO-S(O) 2 OH being approximately as acidic as sulfuric acid itself. The derivatization of these compounds is directed toward replacement of acidic hydrogens.
