PETRUSěVSKI, Vladimir M.  and  RISTESKA, Keti. Chemistry of Alkali Metals 2: On the Reactions of Alkali Metals with Liquid NO₂ and the Nature of the Product. Educ. quím [online]. 2008, vol.19, n.2, pp.142-145. ISSN 0187-893X.

The reactions of sodium and potassium with liquid nitrogen(IV) oxide were performed to check the nature of the product, that was claimed (Nekrasov, 1976) to be MNO₃ (M = Na, K). Both classical chemical reactions and FT-IR spectrometry were used in the course of its analysis. It was proved that the product was indeed nitrate, sometimes containing nitrites as impurities.

Keywords : alkali metals; nitrogen(IV) oxide; nitrogen dioxide; dinitrogen tetroxide; alkali nitrates; alkali nitrites; IR spectroscopy.
