What is the solubility of #PbI_2#?

Answer 1

You need a #K_"sp"# value for #PbI_2#.

Plumbous iodide is insoluble in aqueous solution, and thus the reaction would lead to a yellow precipitate of #PbI_2# as shown.
#Pb(NO_3)_2(aq) + 2KI(aq) rarr PbI_2(s)darr + 2KNO_3(aq)#.
Now of course we could calculate the concentration of #PbI_2# that does go up into solution, but for this need a #K_"sp"# value for #PbI_2#.
#PbI_2(s) rightleftharpoons Pb^(2+) + 2I^-#
#K_"sp"=[Pb^(2+)][I^-]^2# #=# #??#

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
