Sodium tungstate is a kind of white shiny crystalline or crystalline powder, whose chemical formula is Na2WO4. It is weathered in the air. Also, it is insoluble in ethanol, slightly soluble in ammonia, and soluble in water, which is slight alkalinity. It is also known for its anti-diabetic effects.
Sodium tungstate is prepared from tungsten ores used to manufacture tungsten by reducing it. It is used as catalyst for epoxidation of alkenes and oxidation of alcohols into aldehydes or ketones in organic chemistry. And it is applied as a mordent in dyeing, for fireproofing fabrics, weighting silk, reagent pigment, tannins, aceto acetic acid, uric acid as well as decolorizing acetic acid. Also, it is sometimes used as a fireproofing agent.
It is often found as the dihydrate, Na2WO4•2H2O. This salt is a moderately strong oxidizing agent, but finds no common use in the chemistry laboratory.
Researchers have identified the pathways through which sodium tungstate improves pancreatic ding and beta cell proliferation.
