Problem

Lead(II) fluoride, PbF2_2(s), is sparingly soluble in water at 25 °C. (a) Given that log⁡10Ksp=−7.29\log_{10}K_{sp}=-7.29 for PbF2_2 at 25 °C, determine the numerical value of KspK_{sp} to three significant figures. (b) Using the value of KspK_{sp} from part (a), calculate the molar solubility of PbF2_2 (in mol L−1^{-1}) at 25 °C. (c) What mass (in g) of PbF2_2 can dissolve in 250.0 mL of water to produce a saturated solution at 25 °C?
