Lanthanum-140 (t = 1.6 d) is a potent - emitter and fission product that was a crucial utility in the Manhattan Project. It is often recovered from irradiated uranium and its parent isotope 140Ba. Trivalent lanthanum is very insoluble under basic conditions according to the equation:
The solubility product (Ksp) of La(OH)3 is 10-20 M 4. If a carrier solution of 140La is adjusted to pH 11 (pH + pOH = 14), a white precipitate forms. What is the final concentration of La3+?
