Arsenic acid Wikipedia

It is a tetrahedral species of idealized symmetry C3v with As–O bond lengths ranging from 1.66 to 1.71 Å. Being a triprotic acid, its acidity is described by three equilibria: H3AsO4 + H2O ⇌ H 2AsO 4 + H3O (pKa1 = 2.19) H 2AsO 4 + H2O ⇌ HAsO 4 + H3O (pKa2 = 6.94) HAsO 4 + H2O ⇌ AsO 4 + H3O (pKa3 = 11.5)These pKa values are close to those for phosphoric acid. The highly basic arsenate ion(AsO 4) is the pro

Bauxite is the principal ore of aluminum and is a mixture of aluminum oxides and hydroxides that formed from intense chemical weathering of a soil in tropical environments. Soils formed under these conditions are termed laterites. In Arkansas, the aluminum-enriched soils are the result of the decomposition and lateritic weathering of nepheline syenite, an intrusive igneous rock. During the
