Synthesis
Dissolution of metallic polonium in concentrated nitric acid:
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).
