The possibility of plutonium waste leaking from nuclear faciliteis is a serious environmental problem.
If the solubility product of `Pu(OH)_(4)` based on the following potentials measured in acid or basic solution is `K_(sp)`. Then
In `K_(sp) = (-xF)/(RT)`. Find x where 'F' is Faraday's constant
[Given : `Pu^(4+)(aq) + 4e^(-) rightarrow Pu(s)E^(@) = -1.28V`.
`Pu(OH)_(4)(s) + 4e^(-) rightarrow Pu(s) + 4OH^(-)(aq)`
`E=-2.03` V at pH = 14]
