If a saturated solution prepared by dissolving solid BaSO4 in water has [Ba2+]= 1.04*10^5M, what is the value of Ksp for BaSO4?

2 answers

BaSO4 ==> Ba^+2 + SO4^-2

Ksp + (Ba^+2)(SO4^-2)
Solubility BaSO4 = given.
Then (Ba^+) = same
(SO4^-2) = same.
Solve for Ksp.
I'm not to sure what you mean by "the same"
