The corrosion resistance of lithium electrodes in contact with aprotic organic solvents is due to a particular protective film forming on the electrode surface when it first comes in contact witfi tfie solvent, preventing further interaction of the metal with the solvent. This film thus leads to a certain passivation of lithium, which, however, has the special feature of being efiective only while no current passes through the external circuit. The passive film does not prevent any of the current flow associated with the basic current-generating electrode reaction. The film contains insoluble lithium compounds (oxide, chloride) and products of solvent degradation. Its detailed chemical composition and physicochemical properties depend on the composition of the electrolyte solution and on the various impurity levels in this solution. 

With positive elements, other than hydrogen, delinite compounds are usually formed, analogous in composition to oxides. Tims, with silver—... 

Oxidation. The chief use for nitric acid other than in nitration is as an oxidizing agent. As a survey of types of compounds oxidized, conditions, and yields, we present below a summary of procedures appearing in Organic Syntheses, with citation of the collective or annual volume number and page. "Concentrated nitric acid (sp. gr. 1.42) is indicated by its composition, 71% HNO.,. 

For the unsaturated compounds, the conversion rates represent complex functions of the reaction mixture composition. Under the conditions when the reaction exhibits zero order with respect to hydrogen chloride, the kinetics of unsaturated compounds oxidative chlorination is described by the equation ... 

It is essential to preserve the integrity of the sample between the time of collection and the time of analysis. There are, however, several processes that can cause changes in the chemical composition. Examples of these include biodegradation (e.g., of nitrogen- and phosphorus-containing compounds), oxidation (e.g., of Fe(II) and organic compounds), absorption (e.g., of CO2 which affects pFl and alkalinity), precipitation (e.g., removal of CaC03, Al(OH)3), volatilization (e.g., loss of NH3, HCN), and adsorption (e.g., of dissolved metals on the walls of the container).
