Since K is very large, inspection of the above equation shows that 5 must be very close to 0.5. The equation can be readily solved by setting 5 = 0.5 in the numerator and the last term of the denominator, giving:

Forming the ratio of Pu4+ to Pu3+ from the third column of the reaction progress variable table gives:

Thus, essentially all of the initial tetravalent plutonium is reduced to the trivalent state by addition of the ferrous ion solution.

Solution of this equilibrium by the element-conservation method is the subject of Problem 10.15. Problem 10.3 concerns a related ionic equilibrium calculation.

We respect Nature and it gives us its bounty, but in the recent past greedy money hungry corporations have made us all so destructive, so wasteful.
