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-).

  1. 01[Ca2+] = 1 × 0.001 = 0.001
  2. 02[F-] = 2 × 0.001 = 0.002
  3. 03Ksp = (0.001)^1 × (0.002)^2
  4. 04Ksp = 4 × 10^-9
