- Uranium as U(VI) (as the uranyl ion; UO22+) is soluble and moves easily with groundwater, but U(VI) (as uraninite; UO2) is relatively insoluble. Several microorganisms are able to mediate this process. As such, in many uranium-contaminated aquifers, the reduction of soluble uranyl to insoluble uraninite by microorganisms has been proposed as a way to remove the dissolved uranium from water and keep it “locked up” in the subsurface. If the U(VI) is primarily complexed with carbonate (as UO2(CO3)34-), how does that influence the energy yield (or “reducibility”) of the U(VI), assuming “standard” conditions (i.e. not taking concentrations of any products or reactants into account? What about at pH 7? Under what kind of conditions would you expect to find UO2(CO3)34- vs UO22+ (and why)?Are these systems moderated, explain. A. An aqueous solution of plutonium nitrate B.
