At normal laboratory conditions, oxides of nitrogen are to be generated. Which chemicals provide the best results?
Sachin K C
Cu + 4HNO3(60%) → Cu(NO3)2 + 2NO2 + 2H2O
In this reaction, pure nitrogen dioxide is formed only with concentrated nitric acid. But as you can see, it is necessary to dry it from water by passing it through desiccants. It can also be obtained by boiling concentrated nitric acid.
Nitrogen dioxide is a chemical compound with the formula NO 2. It is one of several nitrogen oxides. NO 2 is an intermediate in the industrial synthesis of nitric acid, millions of tons of which are produced each year for use primarily in the production of fertilizers. At higher temperatures it is a reddish-brown gas. It can be fatal if inhaled in large quantity.[8] Nitrogen dioxide is a paramagnetic, bent molecule with C2v point group symmetry.
