Sodium metatungstate is the
inorganic compound with the
formula Na6[H2W12O40],
sometimes written 3Na2WO4·9WO3·H2O. It is also
referred to as
sodium polytungstate...
- In chemistry,
metatungstate refers to the
anion with the
formula [W12O40]8- and
salts derived from this anion. The term also
refers to
protonated derivatives...

acidification produces the very
soluble metatungstate anion, H 2W 12O6− 40,
after which equilibrium is reached. The
metatungstate ion
exists as a
symmetric cluster...
