WebNitrogen (III) oxide, N 2 O 3, is the anhydride of nitrous acid; HNO 2 forms when N 2 O 3 reacts with water. There are no stable oxyacids containing nitrogen with an oxidation state of 4+; therefore, nitrogen (IV) oxide, NO 2, disproportionates in one of two ways when it reacts with water. In cold water, a mixture of HNO 2 and HNO 3 forms.
