What is tungstate formula?

Na2WO4
Sodium tungstate/Formula
CHEBI:63940 – sodium tungstate Sodium tungstate is the inorganic compound with the formula Na2WO4. This white, water-soluble solid is the sodium salt of tungstic acid. It is useful as a source of tungsten for chemical synthesis. It is an intermediate in the conversion of tungsten ores to the metal.

What is sodium tungstate used for?

In organic chemistry, sodium tungstate is used as a catalyst for epoxidation of alkenes and oxidation of alcohols into aldehydes or ketones.

Is tungstate a metal?

Most useful tungsten ores, including scheelite, the naturally occurring form of calcium tungstate, belong to this class of compounds. Alkali metal tungstates are typically water soluble and may be used for their properties in solution.

What is tungstic acid used for?

They are used as catalysts for cracking hydrocarbons and in the dehydrogenation of olefines, in textiles as a mordant, and in the making of plastics (7). Tungstic acid glue has also been suggested as an India rubber substitute (10).

How are tungstate solutions similar to molybdates?

Solutions of tungstates, like those of molybdates, give intensely blue solutions of complex tungstate (V,VI) analogous to the molybdenum blues when reduced by most organic materials. Unlike chromate, tungstate is not a good oxidizer, but like chromate, solutions of tungstate condense to give the isopolytungstates upon acidification.

What is the W-O distance of a tungsten compound?

Orthotungstates feature tetrahedral W (VI) centres with short W–O distances of 1.79 Å. Structurally, they resemble sulfates. Six-coordinate, octahedral tungsten dominates in the polyoxotungstates. In these compounds, the W–O distances are elongated. See the tungstates category for a list of tungstates. Tungstates occur naturally with molybdates.

Which is the simplest ion in a tungstate?

The simplest tungstate ion is WO2−. 4, “orthotungstate”. Many other tungstates belong to a large group of polyatomic ions that are termed polyoxometalates, (“POMs”), and specifically termed isopolyoxometalates as they contain, along with oxygen and maybe hydrogen, only one other element.
