This compound can be made into a milder dehydration agent by increasing its concentration, producing a clear, viscous liquid that is mixed with kieselguhr (“KEE-zel-goor”) in the solid catalyst for the cumene process. The concentration of this compound is often expressed in terms of its anhydride, which is an adamantane-like decaoxide (-5[1])(“deca-oxide”) that deliquesces (“deli-KWESS-iz”) back to this compound. (10[1])Incidentally radioactive gypsum is a major byproduct of the “wet process” of producing this compound, which dominates worldwide sulfuric acid consumption. A slurry of this acid and crushed fluorapatite (“flor-apatite”) are granulated into a triple “super” product whose NPK (-5[1])number can approach (-5[1])0-52-0. (-5[2])One (-5[1])part of this acid is combined with one part hydrogen and two parts ammonia in two-component fertilizers. For 10 points, (10[1])Coca-Cola’s (-5[1])ability to erode (10[1])teeth (-5[1])comes (10[1]-5[1])from what (-5[2])triprotic (-5[1])(“try-pro-tick”) acid, (10[3])whose (10[1])conjugate (10[1])base is phosphate?
