Abstract

In a previous paper (1), the authors presented a system of qualitative microanalysis by means of drop tests based on a sodium carbonate-sodium peroxide separation. As was pointed out at that time, the separation gives two groups, namely the "aqueous" group, which consists mainly of elements that yield water-soluble carbonates and hydroxides, and the "acid" group which is made up chiefly of elements that give insoluble carbonates and hydroxides. It was further pointed out that one of the main advantages of the system offered was that the oxidation by the sodium peroxide yields the elements in a constant state of oxidation, usually the highest. This adjustment of valence has two main advantages; first, since all forms of an element are converted to one common valence, many tests are eliminated; second, the elimination of extra valence forms reduces the possible interferences and makes interference studies much more simple.
