incorrect redirection
[edit]Wikipedia search "nitrogen trioxide" redirects not to Nitrate but here to (di)nitrogen (II) trioxide.
In some situations of chemistry one is to assume the number of the + ion if the - ion allows no other choice: which is NOT the preferred way to leave the notation (it is considered sloppy). But that's not the case here: there IS more than one long known choice, so the redirection is incorrect.
The article for Nitrate is well cited. — Preceding unsigned comment added by 2600:8806:400:1CF0:A4C7:AEA0:F1BE:E7CB (talk) 22:26, 10 April 2018 (UTC)
Not a Solid?
[edit]Why does the article say that it is a solid when its melting point is less than -140 degrees Fahrenheit? I thought that ordinary room temperature and ordinary atmospheric pressure were supposed to be the reference for the state of a substance. Is this because it is a solid at the highest temperature at which it is stable.24.191.117.99 (talk) 02:36, 17 June 2021 (UTC)
Density
[edit]How can the density of N2O3 be higher when it is a gas than when it is a liquid? What conditions are involved? Or is this an error?
Oxidation states of nitrogen
[edit]"All atoms and bonds of dinitrogen trioxide molecule contribute to the resonancy. The oxidation state of the nitrogen atom of the nitroso group is +3, while the oxidation state of the nitrogen atom of the nitro group is +5."
This does not add up. Not sure whether they are really +2 and +4 or, counting inductuve polarization from the additional oxygen, both +3. Olthe3rd1 (talk) 11:08, 11 December 2023 (UTC)
