The Ksp of nickel(II) carbonate, NiCO3, is 1.42×10−7. Calculate the molar solubility, S, of this compound.

Answer 1

...........NiCO3 ==> Ni^2+ + CO3^2-
I..........solid......0.......0
C..........solid......S.......S
E..........solid......S.......S

Ksp = (Ni^2+) + (CO3^-)

Plug in the values from the ICE chart and calculate S in mols/L. .
