Melting point~95 ° C (lit.)
Molecular formula H5O41PW12
Molecular weight 2898.069
Accurate quality 2899.215088
PSA 711.32000
Storage conditions
Closed, cool, and dry place at 2-8 ° C
Stability
Stable at room temperature and pressure
Avoid light, open flames, and high temperatures.
Extremely soluble in water [about 85% by mass], as well as in other electron donating organic solvents such as acetone, DMF, etc. Phosphotungstic acid is completely dissociated in aqueous solution. Three kinds of Phosphotungstic acid hydrates (H3PW12O40 · nH2O, n=6, 21 and 29, respectively) were studied by X-ray technology and neutron diffraction method. The stable acidity range of PW12 in aqueous solution is limited, and when the pH is 1.5-5, it will quickly transform into a vacant PW11 anion.
