Uses Phosphotungstic acid hydrate has been a useful histology stain for cell specimens.
Uses 12-Tungstophosphate hydrate is used in histology as a component for staining of cell specimens. It binds to fibrin, collagen and fibers of connective tissues. It is also used to replace the anions of dyes from these materials. In solution, it acts as a homogeneous catalyst and involved in the hydrolysis of propene to give 2-propanol. It is supported with alumina and silica and act as a heterogeneous catalyst involved in the dehydration of 2-propanol to propene and methanol to hydrocarbons. In analytical chemistry, it is used to precipitate proteins and termed as "universal" precipitant for polar proteins.
Uses
Phosphotungstic acid hydrate may be used as a staining agent for the transmission electron microscope (TEM) imaging of cetyltrimethylammonium bromide (CTAB) coated gold nanorods.
It may be used in the preparation of:
Phosphotungstic acid doped ormosil hybrid networks.
Niobia supported phosphotungstic acid (PTA) catalysts.
Titanium dioxide (TiO2) nanoparticles /phosphotungstic acid (HPW) films.
