Ksp vs Molar Solubility
公式
## 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.
计算示例
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
常见问题
What is Ksp?
The equilibrium constant for dissolution of a sparingly soluble ionic compound, equal to the product of ion concentrations raised to stoichiometric powers.
What does a larger Ksp mean?
Greater solubility. The compound dissolves more and produces higher ion concentrations.
Can Ksp predict precipitation?
Yes. If ion product Q > Ksp, a precipitate forms. If Q < Ksp, more can dissolve.
