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 …

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 …

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 …

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 …

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 …

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 …

Is there a logical way to deduce this or should one just memorize that "Al and Zn reduce $\ce{NO3-}$ to ammonia in basic solutions"? I learned that the reaction is called "a nitrate test …
