What [I^-]should be maintained in KI(aq) to produce a solubility of 1.9×10−5mol PbI2/L when PbI2 is added?

(sorry i cant find it under the posted questions )

Write the Ksp expression. Solve for concn I^-. You know Ksp and Pb^+2 since Pb^+2 is same as concn PbI2. That leaves just the one unknown of I^-.
