Ni­tro­gen â¦ Nitric acid | HNO3 | CID 944 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more. I thought it would be N_2O < NO_2 < NaNO_2 = HNO_3 < NH_4Cl But apparently its wrong. To find the oxidation state using Lewis structure, I have to compare the electronegativity of the bonded atoms and assign the â¦ 6. So here nitrogen exhibits positive oxidation state 0. reply. In NOCl, the nitrogen has an oxidation state of +3. Ni­tro­gen has an ox­i­da­tion state of +3 in the ox­ide NâOâ (a dark blue liq­uid with acidic prop­er­ties) and ni­trous acid HNOâ. The book asks me to find the oxidation state of nitrogen in the compound below (the structure is not the one given in Wikipedia for HN3):. It's clear that as we decrease the concentration of nitric acid, we get more and more reduced nitrogen: in $\ce{NO2}$, the oxidation state of N is ($\mathrm{+4}$), then it goes to zero in $\ce{N2}$ (when we use $\mathrm{10\%}$ strong $\ce{HNO3}$).
