A Dictionary of Chemistry
Metatungstic acid (v. 911) is, according to Scheibler {Jahresb. 1860, p. 157), a
more delicate reagent for alkaloids than phosgholybdic acid, all such bases
being precipitated by it in white flocks. To obtain this reaction it is not necessary
to use ...

Metatungstic Acid. Soluble Modification of lungstic Acid. — -This acid is mostly
produced in the decomposition of tungstates by the stronger acids at ordinary
temperatures ; also by the action of tungstic acid on tungstates. Pure metatungstic

Progress in Inorganic Chemistry
The titration curves for freshly prepared metatungstic acid anhydride and WO3-%
H2O are similar to that for the dihydrate, whereas an aged metatungstic acid
anhydride behaves more like WO;;-H20 (38). Potentiometric titration of the ...

The results of these studies lay at the basis of the synthesis of high purity
polytungstic acids obtained in good yields as it is the case with the metatungstic
acid. The ion exchange can be partially or completely performed, using an
excess of ...

Handbook of Inorganic Electrochromic Materials
Spraying of aqueous solutions of metatungstic acid (H6W12O39) was reported
by Hurditch (1583) and by Zeller and Beyeler (3791). Films with good
electrochromism were obtained for 150 < ts < 200°C, whereas no
electrochromism was ...

The low-temperature endotherm is attributed to the removal of water whereas the
high-temperature exotherm signals the decomposition of the anion. The authors
note that metatungstic acid H8[W12O40]ÁxH2O decomposes at 50 ...

This molecule and its antithesis, the metatungstic acid molecule, are notable for
their incorporation of two nonlabile hydrogen atoms somewhere in the interior.
