Question

Find the molar solubility of PbI2. Ksp=7.1e-9, then given the molar solubility from the previous answer, what is the solubility of PbI2, in grams per litre?

Knowing this, would PbSO4 (Ksp=1.6e-8) have a higher molar solubility than PbI2? (I'm thinking PbSO4 would be higher, since the Ksp is larger?)

Answer 1

Ksp of Pb 1₂ = 7.1x109 . PbIz is a Aba type of salt Ksp = 4 3 3 = 7-1X109 co 3's 1.775*109 Sal21x103M. -3 2 x 70 <3 molar solubility of pb]z al-21x10m S= 1.21x10 mole / ut s= 1.21 x 10 x 460 gm llit S = 557081x10@gm lit BO S = 0.5578 gm lat solubility of Pb I 2 = 0.5578 emput kop of pbsou = 106x108 pbson, is AB type of salt Kpp = 8² 166x108 S = 1.27x16 "M . -4 molar solubility of pbsou = 1127*10m

Molar solubility of PbI2 is greater than PbSO4

Thank you ?

All the best.
