PbI2==> Pb^+2 + 2I^-
Ksp = (Pb^+2)(I^-)^2
Look up Ksp, plug in the solubility you want to maintain for (Pb^+2) and solve for (I^-)
what [I-]should be maintained in KI(aq) to produce a solubility of 1.3*10^-5 mol PbI2/L when PbI2 is added?

thank you DrBob222!!!
Hands down for me. The answer is given below just saved your life.
What should be maintained in to produce a solubility of 1.3×10−5 when is added?
Express your answer using two significant figures.
=2.3×10−2 M
Correct
