CAS 7783-03-1: Tungstic acid (H2WO4)

Description: Tungstic acid, with the chemical formula H₂WO₄ and CAS number 7783-03-1, is an inorganic compound that contains tungsten in its highest oxidation state. It typically appears as a white or yellowish solid and is soluble in water, forming a colloidal solution. Tungstic acid is known for its acidic properties, exhibiting a pH lower than 7 in solution, and it can act as a weak acid. It is primarily used in various applications, including catalysis, as a precursor for tungsten compounds, and in the production of tungsten-based materials. The compound is also utilized in analytical chemistry for the precipitation of certain metal ions. Tungstic acid can be produced through the oxidation of tungsten trioxide (WO₃) with water or through the reaction of tungsten salts with strong acids. Due to its chemical properties, it is important to handle tungstic acid with care, as it can be hazardous in concentrated forms. Overall, tungstic acid plays a significant role in both industrial and laboratory settings.
