An example of the different points of view and different tastes in the matter of acid-base definitions was provided to one of the authors in graduate school while attending lectures on acid-base chemistry from two professors. One Felt that the solvent system was very useful, but that the Lewis concept went too far because it included coordination chemistry. The second used Lewis concepts in all of his work, but felt uncomfortable with the Usanovich definition because it included redox chemistry To the latter s credit, however, he realized that the separation was an artificial one, and he suggested the pyridine oxide example given above. 

Like acid/base chemistry, redox chemistry is strongly dependent on the solvent. The susceptibility of the solvent to oxidation or reduction will obviously place restrictions on the scope of redox chemistry which can be studied in it. In the case of water, we have to consider ... 

To characterize the H-coal samples separated by acid-base chemistry, a quantitative analysis of several oxidative degradation products proved to be useful. Chosen for this purpose were the methyl esters of malonic, succinic,... 

There are no sharp dividing lines between subfields in chemistry. Many of the subjects in this book, such as acid-base chemistry and organometallic reactions, are of vital interest to organic chemists. Others, such as oxidation-reduction reactions, spectra. 

Besides acid-base chemistry, combining two elements that have similar properties sometimes gives mixed oxides. An example is formation of -Al203-Ga203 by the reaction of aluminum alkoxide and gallium acetylacetonate. A linear relationship between the lattice parameter of the solid solution and the composition of the two starting materials is observed. Since the products have particle sizes in nano scale with quite large surface areas, reaction mechanisms are not yet fully elucidated, but statistical decomposition of the intermediates seems to be most plausible. 

Like most polynuclear oxy complexes and the surfaces of oxide minerals, these dimers are amphoteric in water and can dissociate by pathways that involve either proton uptake at a hydroxyl bridge or proton release from a bound water molecule. Therefore the stability of a dimer relates closely to its Bronsted acid-base chemistry. The decomposition pathways for hydroxy-bridged dimers are well understood from studies of...
