Nitrogen aqueous chemistry

The solubility of nitrogen(lll) (that is, HONO + N02 ) is fairly high, and its aqueous chemistry is potentially interesting. Pandis and Seinfeld (1989a) suggested that its most important aqueous-phase reaction is with OH ... 

Aqueous Chemistry and Complexes of Titanium(iii). Aqueous solutions of the [Ti(H20)6]3+ ion can be readily obtained by reducing aqueous Ti(iv) either electrolytically or with zinc. The violet solutions reduce oxygen and hence must be handled in a nitrogen or hydrogen atmosphere ... 

Let us now consider the oxygen chemistry stepwise from O2 to H2O2 via HO2 (Chapter 5.3.5.1) and then discuss O3 chemistry (Chapter 5.3.5.2) where OH will play a central role as the detergent of water or, in other words, in the oxidation of contaminants such as organics, sulfur and nitrogen species. The combination of aqueous chemistry with air chemistry is described in Chapter 5.3.6.

Obsolete uses of urea peroxohydrate, as a convenient source of aqueous hydrogen peroxide, include the chemical deburring of metals, as a topical disinfectant and mouth wash, and as a hairdresser s bleach. In the 1990s the compound has been studied as a laboratory oxidant in organic chemistry (99,100). It effects epoxidation, the Baeyer-Villiger reaction, oxidation of aromatic amines to nitro compounds, and the conversion of sodium and nitrogen compounds to S—O and N—O compounds.

It is known from studies carried out over many decades that oxides of nitrogen at high concentrations dissolve in aqueous solution and react to form species such as nitrate and nitrite. With the focus on acid deposition and the chemistry leading to the formation of nitric and sulfuric acids during the 1970s and 1980s, a great deal of research was carried out on these reactions at much lower concentrations relevant to atmospheric conditions (for reviews, see Schwartz and White, 1981, 1983 and Schwartz, 1984). 

Barbara J. Finlayson-Pitts is Professor of Chemistry at the University of California, Irvine. Her research program focuses on laboratory studies of the kinetics and mechanisms of reactions in the atmosphere, especially those involving gases with liquids or solids of relevance in the troposphere. Reactions of sea salt particles to produce photochemically active halogen compounds and the subsequent fates of halogen atoms in the troposphere are particular areas of interest, as are reactions of oxides of nitrogen at aqueous and solid interfaces. Her research is currently supported by the National Science Foundation, the Department of Energy, the California Air Resources Board, the Dreyfus Foundation, and NATO. She has authored or coauthored more than 80 publications in this area, as well as a previous book, Atmospheric Chemistry Fundamentals and Experimental Techniques.
