1. Analogously, nitric acid is HNO 3, and nitrous acid , HNO 2. 2. Upon protonation, the unstable weak acid nitrous acid is produced. 3. Nitrosyl fluoride reacts with water to form nitrous acid , which then forms nitric acid: 4. With nitrous acid aspergillomarasmine A is deaminated, and isoserine with aspartic acid is formed. 5. The presence of nitrous acid can cause transition mutations, by converting cytosine to uracil. 6. Formally they are alkyl esters of nitrous acid . 7. The molecule can also be viewed as the mixed anhydride of sulfuric acid and nitrous acid . 8. In organic chemistry the NO 2 group is present in nitrous acid esters and nitro compounds. 9. The sodium nitrite is first converted to nitrous acid which then forms the electrophilic intermediate dinitrogen trioxide. 10. The presence of small amounts of nitrous acid ( HNO 2 ) greatly enhance the rate of reaction.
