Sulfonic Acids
A sulfonic acid (or sulphonic acid) refers to a member of the class of organosulfur compounds with the general formula RS(=O)2–OH, where R is an organic alkyl or aryl group and the S(=O)2–OH group a sulfonyl hydroxide. A sulfonic acid can be thought of as sulfuric acid with one hydroxyl group replaced by an organic substituent. The parent compound (with the organic substituent replaced by hydrogen) is the hypothetical compound sulfurous acid. Salts or esters of sulfonic acids are called sulfonates.

Famous quotes containing the word acids:
“The new American finds his challenge and his love in the traffic-choked streets, skies nested in smog, choking with the acids of industry, the screech of rubber and houses leashed in against one another while the townlets wither a time and die.”
—John Steinbeck (1902–1968)
