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 valence electrons instead of 5, thus being able to form another covalent bond with the extra oxygen, forming $\ce{NO3}$. Is this the correct line of thinking?

2015年6月4日 · $\begingroup$ $\ce{BiO(NO3)}$ could probably be added to the list … to quote a fellow student in the ion lottery practical course. 'Found nitrate, didn’t dissolve; only one insoluble nitrate.' (Note: He meant that we wouldn’t have gotten any others.) $\endgroup$

2017年10月26日 · The brown ring formed in the confirmatory test for the nitrate ion is due to the complex called nitroso ferrous sulphate, or pentaaqua nitrosyl iron (II) sulfate with the formula $\ce{[Fe(H2O)5NO]SO4}$.

2018年11月18日 · There are two ways to think of it. First: draw out the (major) contributing Lewis structures for both ions. Each iin has one pi bond, but it's shared between two linkages in $\ce{NO2^-}$ ion versus three linkages in the $\ce{NO3^-}$ ion. So the $\ce{NO3^-}$ ion has less pi bonding in each linkage making those bonds weaker overall.

2015年1月30日 · 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 confusing to me. Some people show dative/co-ordinate bonds, whereas others show a positive charge on nitrogen. Which should be considered as correct one?

2023年5月16日 · Increase the concentration of $\ce{NO3^-}$ in the solution to prevent formation of aqua complexes in accordance with Le Chatelier's Principle, as explained in the section Hydration Isomerism of $\ce{Fe(NO3)3}$ below.

2012年6月6日 · Because, unlike in other metal dissolution reactions, the $\ce{H+}$ of $\ce{HNO3}$ isn't reduced—the $\ce{NO3-}$ is. The following data and balanced reactions are taken from Wikipedia :

2014年12月18日 · The nitrate ion $\ce{NO3-}$ is what I like to call a Y-aromat since it has some similarity in the electronic structure. The bonding situation is very comparable to benzene. The resonance structures, however, look much more complicated.

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 involved, $\ce{Cu}$ must be considered in the reduction potential as well.
