Polonium tetranitrate is an inorganic compound, a salt of polonium and nitric acid with the chemical formula Po(NO3)4. [1] The compound is radioactive, forms white crystals. [2] [3]
Dissolution of metallic polonium in concentrated nitric acid:[ citation needed]
Polonium(IV) nitrate forms white [4] or colorless crystals. [5] It dissolves in water with hydrolysis.
It disproportionates in aqueous weakly acidic nitric acid solutions:
The polonium(II) ion (Po2+) is then oxidized by nitric acid to polonium(IV).
