Infobox references

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]

Po+8HNO3 → Po(NO3)4+4NO2↑+4H2O

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:

2Po(NO3)4+2H2O → PoO2(NO3)2↓+Po2++2NO3−+4HNO3

The polonium(II) ion (Po2+) is then oxidized by nitric acid to polonium(IV).
