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]
Synthesis
Dissolution of metallic polonium in concentrated nitric acid:[citation needed]
Physical properties
Polonium(IV) nitrate forms white[4] or colorless crystals.[5] It dissolves in water with hydrolysis.
Chemical properties
It
disproportionates
in aqueous weakly acidic nitric acid solutions:
The polonium(II) ion (Po2+) is then oxidized by nitric acid to polonium(IV).
