I understand how the nitrite NOX2 N O X 2 ion can be formed and have a negative charge, but the nitrate NOX3 N O X 3 ion is confusing me. I made some simple drawings to try to explain what I don't understand: Does the "electron from outside" that the oxygen receives, as indicated in the drawing, comes from the nitrogen atom? If so, then the N atom would be left with only 4 …

Jan 30, 2015 · What's the oxidation state of nitrogen in $\\ce{NO3-}$ ion. Simple calculation depicts that it's $+5$. But second period elements never show variable oxidation states. And it's structure is so confu...

Jun 4, 2015 · All the examples of $\\ce{NO3-}$ salts are soluble in water (all that I know about). Is it always so or there is some salt which doesn't dissolve in water? If so what is the reason behind it?

Feb 7, 2018 · Can anyone explain how the bonding is formed in NO3 because I can't understand how N can satisfy electron hunger of 3 oxygen atom

Oct 26, 2017 · Today in our practicals I observed that when I did the wet test for nitrate (Making a 1 ml solution of salt solution+$\\ce{FeSO4}$ solution+hot concentrated $\\ce{H2SO4}$); The brown ring appeared fo...

How does ammonia evolve here? Is it that we get hydrogen gas evolving in the reaction between Al and NaOH and this gas reacts with the NO3 anion? Is there a logical way to deduce this or should one just memorize that "Al and Zn reduce NOX3X− N O X 3 X − to ammonia in basic solutions"? I learned that the reaction is called "a nitrate test using Devarda's alloy ", but there …

Nov 18, 2018 · For the nitrate ion (NO3-), there is one double bond that leads to resonance amongst all three of the nitrogen-oxygen bonds. This effectively gives each bond the characteristic of 1.3 bonds, and slightly longer than in the nitrite ion.

There are two copper blocks sitting in the $\\ce{Cu(NO3)2 (aq)}$ solution, a battery is attached onto both of them, providing enough energy to start the reaction. Since solid pieces of copper are

May 16, 2023 · I want to make particular concentration of ferric ions from $\\ce{Fe(NO3)3.9H2O}$, and then I found this video It says that we have to add nitric acid to prevent iron from hydrolysis, what does it m...

Oct 22, 2018 · ManishEarth did a good job explaining already. Perhaps I could point out one more you could think of to understand why nitric acid has such a high reduction potential. The nitrogen centre in nitric acid is in +5 oxidation state, which is also the highest known oxidation state of nitrogen. As a result, the acid exists in high energy state to begin with as it is really unstable.
