Abstract

Besides being of practical importance in the preparation of compounds, the valence of an element is of theoretical significance because it is a clue to the electronic structure of the atom. In the case of elements which have several valences the relative stability and the means of changing from one state of oxidation to another are also important.

Uranium has valences of three, four, five, and six, but the reactivity of the trivalent uranium ion causes difficulties in the preparation of its compounds. Dr. Scott L. Kittsley in his investigation of the trivalency of uranium found that it is possible to convert hexavalent uranium to the trivalent state by reduction with nascent hydrogen. This type of reduction appeared to be a means of preparing compounds of trivalent uranium. In the following investigation an attempt was made to precipitate a salt of trivalent uranium after reduction from the hexavalent state.
