Sulfuric acid is the most abundant product of the chemical industry. It is used in the refining of metals and in the manufacture of a wide variety of substances. It is used for the pickling of steel to retard corrosion, in the refinement of petroleum, and in the manufacture of fertilizers.
1 Sulfuric acid is important in the production of fertilizers such as ammonium sulfate (sulfate of ammonia), (NH 4) 2 SO 4, and superphosphate, Ca(H 2 PO 4) 2, which is formed when rock phosphate is treated with sulfuric acid. 2  Sulfuric acid is used to remove oxides from iron and steel before galvanising or electroplating. Concentrated sulfuric acid (18M) is used as a dehydrating agent, that is, to remove water, since it has a tendency to form hydrates such as H 2 SO 4 .H 2 O, H 2 SO 4 .2H 2 O, etc. 2  2, O 2, CO 2 and SO 2. 3  12 H 22 O 11 (s), (cane sugar) to produce a spongy mass of carbon:
