sodium tungstate dihydrate boiling point

Sodium tungstate dihydrate, or tungstic acid sodium salt dihydrate, is a chemical compound that can be found in nature in such forms as feldspars and sodalite. It is also a synthetic compound, manufactured through the Colin reaction using sodium hydroxide and tungsten oxide. The boiling point of tungstic acid sodium salt dihydrate is 665 °C, which is significantly lower than that of the anhydrous form (CAS number 10213-10-2). Sodium tungstate has promising biological properties, such as antitumor and anti-inflammatory effects. In addition, the chemical has excellent photocatalytic properties and can be used as a corrosion inhibitor in metal production processes.

This compound is soluble in water, slightly alkaline and insoluble in alcohol. It occurs as white orthorhombic crystals or powder. Sodium tungstate is used as an analytical chemical reagent, mordant and pigment and is a catalyst in the manufacture of metal tungsten, tungstic acid and tungstate, as well as for fabric fire retardants and as a precipitating agent for alkaloids.

This compound is considered to be nontoxic, but it can cause eye irritation if it comes into contact with the eyes. Moreover, if swallowed, it may be harmful to the respiratory tract. In case of an accident, you should rinse your eyes immediately with water while removing any contaminated clothing and seek medical aid immediately. Additionally, it is also recommended to avoid direct contact with skin as it can be irritating. Lastly, if discarded chemical waste is left in the environment, it is important to follow federal and state hazardous waste regulations to ensure proper disposal.
