Solubility product Ksp (Ksp = [M]ˣ[X]ʸ for sparingly soluble salt)
jee-mainjee-advancedneet-ug
Ksp = [M]ˣ[X]ʸ for sparingly soluble salt
What each symbol means
| Symbol | What it stands for |
|---|---|
| s | Molar solubility related via stoichiometry |
| K_sp | Equilibrium constant for dissolution (solid omitted) |
When to use this
Saturated solution at constant T; activities ≈ concentrations for dilute ions; common ion reduces s but Ksp unchanged (same T).
