| Found in | Wikipedia, July 19, 2012 (Tungstic acid. Refers to hydrated forms of tungsten trioxide, WO₃. The simplest form, the monohydrate, is WO₃.H₂O, the dihydrate WO₃.2H₂O is also known. The solid state structure of WO₃.H₂O consists of layers of octahedrally coordinated WO₅(H₂O) units where 4 vertices are shared. The dihydrate has the same layer structure with the extra H₂O molecule intercalated between the layers. The monohydrate is a yellow solid and insoluble in water. The classical name for this acid is 'acid of wolfram'. Other names: Orthotungstic acid. Molecular formula: H₂WO₄) Chemical book website, July 19, 2012 (Chemical Name: Tungstic acid. Synonyms: O2W(OH)2; Tunstic acid; Wolframic acid; TungsticAcidGr; Tungstic(VI) acid; Orthotungstic acid; Tungstate,dihydrogen. Molecular formula: H2O4W) Collins English dict., c2003, via TheFreeDictionary website, July 19, 2012 (tungstic acid (Chemistry / Elements & Compounds) any of various oxyacids of tungsten obtained by neutralizing alkaline solutions of tungstates. They are often polymeric substances, typical examples being H₂WO₄ (orthotungstic acid), H₂W₄O₁₃ (metatungstic acid), and H₁₀W₁₂O₁₄ (paratungstic acid)) TheFreeDictionary thesaurus, via WWW, July 19, 2012 (tungstic acid - an oxyacid of tungsten (often polymeric in nature) formed by neutralizing alkaline tungstate solutions) WolframAlpha website, July 19, 2012 (tungstic acid. IUPAC name: dihydroxy-dioxotungsten. Alternate names: dihydroxy-diketo-tungsten; dihydroxy-dioxo-tungsten; orthotungstic acid; tungstic(VI) acid; tunstic acid; wolframic acid. Formula: H₂WO₄.
