what is the molarity concentration of lead cation in a saturated solution of lead sulfate? Ksp(PbSO4)= 6.3x10^-7 and what is the solubility of PbSO4 in g/ml?
show clear equations and answers
PbSO4 ------> Pb+2 + So42-
s s
Ksp = [Pb+2][So42-]
6.3x10^-7 = s*s
s2 = 6.7*10-7
s = 8.185*10-4 M
[Pb+2] = 8.18*10-4 M
molarity of PbSO4 = 8.185*10-4 mole/L
= 8.185*10-4mole/L *303.26g/mole
= 2482.18g/L
= 2482.18g/1000ml
= 2.48218g/ml
