Question

Calculate the solubility at 25 C of PbCo, in pure water and in a 0.0150 M Na, CrO solution. You'll find data in the ALEKS Data tab. Round both of your answers to 2 significant digits. solubility in pure water: solubility in 0.0150 M NaC10, solution: x 5 ?

Answer 1

Ksp (PO GOO4) = 1.3x10-14 i solubility in peure water - PbGrOq = P6+2 + x 69 0 2 x x → solubility (molelilit ) Ksp = 1.8x10-14 2 = 1-3416 *10*7 molellit Solubility cgm ldit) = 1.3416x10-7* 323-19 gm/hit = 4.3359 x10-5 gm lit
