They are formed by the action of HNO3 on metals, metallic oxides and also by the neutralization of Alkalis with HNO3
NB: All trioxonitrate (v) salts are soluble in water and easily decomposed by heating.
|Metal||Decomposition of the Corresponding trioxonitrate (v)|
|These ones decompose to the corresponding dioxonitrate (iii) and oxygen
e.g 2NaON3(s) → 2NaNO2(s) + O2(s)
|These trixoninitrate decompose on heating to form the corresponding metallic oxides, oxygen and reddish-brown Nitrogen (iv) oxide
|These ones decompose on heating to the corresponding metal, oxygen and reddish-brown Nitrogen (iv) oxide.|
