incorrect redirection
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?
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
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
"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)
