Sulfonic acid

A sulfonic acid (or sulphonic acid) refers to a member of the class of organosulfur compounds with the general formula R−S(=O) 2 −OH where R is an organic alkyl or aryl group and the S(=O) 2 (OH) group a sulfonyl hydroxide As a substituent it is known as a sulfo group A sulfonic acid can be thought of as sulfuric acid with one hydroxyl group replaced by an organic substituent
