  3. Exam 3 submitted via Adobe reader submit form.

    I am not sure about my answer for number 7, because I couldn't find a a solubility expression for PuO2 in the lecture notes or in literature, so I guessed one that included OH- to incorporate pH in my answer. I remember this being on quiz 11, but I couldn't find an answer key to that to check my expression.

    1. K=[Pu4+][OH-]^4

      Because PuO2 is dissolved in water.
      PuO2+(H20)-->(Pu4+) + 4(OH-) + (H20)

    3. The Ksp is correct above. An example is given for UO2 on page 20 of lecture 11 on speciation.

  8. For question 6, why is Er not included as part of the answer? In lecture 12 slide 54, though only slightly studied, the table says that lanthanides should form a separate phase. Eu was included in the answer, but not Er.
