Ksp vs Molar Solubility
How to Calculate Ksp
Formula
For A_mB_n dissolving: Ksp = (m×s)^m × (n×s)^n
Where s is the molar solubility, m and n are stoichiometric coefficients.
Example Calculation
CaF2 molar solubility = 0.001 M (1 Ca2+, 2 F-).
- 01[Ca2+] = 1 × 0.001 = 0.001
- 02[F-] = 2 × 0.001 = 0.002
- 03Ksp = (0.001)^1 × (0.002)^2
- 04Ksp = 4 × 10^-9
