General solvosystem concept

Therefore, the generalized solvosystem concept proposed above is applicable to the description of protic and aprotic solvents, although just for this case this does not allow us to obtain basically new results. As for the case of ionic melts, it is more important, since the theoretical basis of acid-base interactions in this kind of solvents is not developed so extensively. Nevertheless, there are many results on oxoacidity obtained in ionic solvents of the first and the second kinds, which have been treated in a proper way. 

Hence, on the basis of the generalized solvosystem concept it is possible to formulate the main distinctive features of different kinds of high-temperature ionic melts as media for acid-base interactions by the Lux-Flood method. 

The analysis of the literature data, taking into account the generalized solvosystem concept introduced in Part 1, gives a possibility of revealing the... 

Nevertheless, the behaviour of oxide-containing melts as a kind of background for acid-base reactions can be described in a manner similar to the solvosystem concept. However, for this purpose the solvosystem concept should be generalized in some ways. As mentioned above, the main object in the basis of Franklin s solvosystem concept is a molecular solvent prone to auto-ionization, and this process results in the formation of small concentrations of cations and anions of the solvent. Water, glycol, different spirits and some other room-temperature liquids are to be mentioned as typical examples of such solvents. 

The above speculations allow us to determine the statements of the classic solvosystem concept which should be generalized for the case of non-dissociated and ionic solvents ... 

However, the practice of investigations of acid-base equilibria consists in studies of the reactions with the transfer of definite particles (acid or base) in different solvents, irrespective of the fact whether they are prone to dissociation with the formation of given acid (base), or not. In order to give the most general formulation of the solvosystem concept we should divide the solvent in relation to the initially chosen definition of acids and bases (definition of acidic and basic particles).
