Uses of sulfuric acid SOLVER CHEM Production process How is sulphuric acid formed Quora

By far the largest amount of sulfuric acid is used to make phosphoric acid used in turn to make the phosphate fertilizers calcium dihydrogenphosphate and the ammonium phosphat It is also used to make ammonium sulfate which is a particularly important fertilizer in sulfur deficientBoth as an industrial product and as a pollutant acid rain it is formed by the reaction of SO2 O2 and H2O The reactions are SO2 1/2 O2 == SO3 and SO3 H2O == H2SO4 In the atmosphere the hydroxyl radical HO catalyzes the reaction In industry a vanadium compound is used as the catalyst
