Mechanistic explanation has been reported for the reaction of
nitrous acid and nitrosonium ion N[O.sup.+] with oximes by Kliegman and Barnes [6].
The formation of gaseous
nitrous acid (HONO): a key determinant of tropospheric ozone and fine particles, Final Report for Contract No.
It has been known for some twenty years that the decomposition of
nitrous acid in light frees up hydroxyl radicals that spark the ozone production cycle.
Stirring of reaction mixture was continued for 1h more maintaining the same temperature, with a positive test for
nitrous acid on iodo paper.

nitrous acid (FNA) in wastewater treatment plants," Water Research, vol.
During such episodes, she adds, there seems to be an ongoing supply of
nitrous acid to maintain OH levels, which raises the question of where that supply is stored.
The induced mutagenesis involving radiations (like ultraviolet or gamma rays) or chemicals (like alkylating agents or
nitrous acid) has been attempted to increase the metabolic performance of bacterial strains for better amylase production (Daba et al.
Further, although
nitrous acid levels typically reach 5-15 ppb by volume indoors and 30 ppb by volume in vehicles, concentrations as high as 100 ppb by volume have been measured indoors.
Hugo Destaillats and colleagues from Lawrence Berkeley National Laboratory (California, USA) discovered that nicotine reacts with a common indoor air pollutant found in smokers' homes and cars, called
nitrous acid (HONO), to form carcinogenic compounds known as tobacco-specific nitrosamines (TSNAs).
At the same humidity, [NO.sub.2] can also react directly with surfaces to form the weaker -- though still salt-producing --
nitrous acid.
Hydralazine has been determined by GC after derivatization with
nitrous acid [18] or with acetyl acetone [19, 20] using packed column.
One of Murphy's discoveries, published this past December in Nature Geoscience, is that
nitrous acid, a primary contributor to smog, cannot survive exposure to sunlight but is continually refreshed by spending its nights hiding in soil.
