The formula
for MₓAᵧ: Ksp = xˣ × yʸ × s^(x + y)
A molar solubility s releases xs of the cation and ys of the anion.
What to watch out for
The default values are silver chloride in water. Only compare Ksp values directly between salts with the same ion ratio.
Frequently Asked Questions
What is Ksp if silver chloride dissolves at 1.3 × 10⁻⁵ mol/L?
s² = 1.7 × 10⁻¹⁰.
What is the solubility of a 1:2 salt with Ksp 4 × 10⁻¹¹?
Ksp = 4s³, so s is 2.15 × 10⁻⁴ mol/L.
