About the Ksp Calculator
A free tool for converting between Ksp and molar solubility for any salt stoichiometry.
What it is
This calculator uses Ksp = x^x ยท y^y ยท s^(x+y) to convert between the solubility product constant and molar solubility for a salt AโBแตง, given the number of cations (x) and anions (y) it dissociates into.
Features
Any stoichiometry
Works for 1:1, 1:2, 2:1, 2:3, and any other AโBแตง ratio.
Solve either direction
Ksp to solubility, or solubility to Ksp.
Scientific notation
Results formatted for readability at any magnitude.
