Calculate the molar solubility of FeCO3 . How many grams of FeCO3 are present in 15.0 L of a saturated FeCO3 solution?

Answer 1

...........FeCO3 ==> Fe^2+ + CO3^2-
I......................0.......0
C......................x.......x
E.......................x.......x

Ksp = (Fe^2+)(CO3^2-)
Substitute from the ICE chart and for Ksp (look up that value) and solve for x = solubility
