Description Arsenic acid, H3Aso4.?H20, white translucent crystals, soluble in water and alcohol; used in insecticides, glass making, and defoliants. Also known as orthoarsenic acid. Arsenic acid has the molecular formula H3AsO4. More descriptively written as AsO(OH)3, this colorless acid is the arsenic analog of phosphoric acid. Arsenate and phosphate salts behave very similarly. Arsenic acid as such has not been isolated, but only found in solution where it is largely ionized. Its hemihydrate form (H3AsO4·1/2H2O) does form stable crystals. Crystalline samples dehydrate with condensation at 100 °C. Arsenic acid is a tetrahedral species of idealized symmetry C3v with As—O bonds lengths ranging from 1.66 to 1.71? . Being a triprotic acid, its acidity is described by three equilibria: H3AsO4 ? H2AsO4- + H+ (pk1 =10-2.19) H2AsO4 ? 5HasO4 2- + H+ (pk2 = 10-6.94) HasO4 2 ? 5AsO4 3- + H+ (pk3 = 10-11.5)
