Calculate the solubility of pbcro4 in water at 25°c . you'll find ksp data in the aleks data tab.

According to the reaction equation:

PbCrO4 ↔ Pb2+   + CrO42- 

so, when the Ksp expression = [Pb2+] [CrO42-]

when the Ksp =2.8 x 10^-13 

when the solubility is the amount of solute that dissolved in a unit volume of a solvent so, we can assume solubility = X

by substitution on Ksp expression:

∴2.8 x 10^-13 = X*X

∴X = √(2.8 x 10^-13)

      = 5.29 x 10^-7 M

∴ the solubility = X = 5.29 x 10^-7

Mass of water is smething that you froma drug test or sum girl ya
