Annotation
This lecture describes the problems of using and advantages of non-aqueous solvents in analytical chemistry. Division of solvents and their basic characteristics from the point of view of work in non-aqueous media is discussed. Acidity and basicity in non-aqueous media.
The using of non-aqueous media in volumetric analysis, spectrophotometry, electrochemistry and in separation methods. The attention is also focused on the selection of solvents, their purification. Also theoretical aspects and advantages of work in non-aqueous solvents are discussed, namely at analysis with organic and biologically active substances.
