💎Ksp Calculator

For a salt AₓBᵧ, convert between the solubility product (Ksp) and molar solubility (s).

Cation subscript (x)

Anion subscript (y)

Ksp

Molar Solubility s (mol/L)

Default: AB₂ type salt (like Mg(OH)₂) with s = 1×10⁻⁵ mol/L. Leave Ksp or s blank to solve for it.

This Ksp calculator converts between the solubility product constant and molar solubility for a sparingly soluble salt AₓBᵧ that dissociates as AₓBᵧ ⇌ xAⁿ⁺ + yBᵐ⁻. Using the ICE table result [A] = xs and [B] = ys, the solubility product is Ksp = (xs)^x × (ys)^y = x^x · y^y · s^(x+y).

Enter the salt's stoichiometry (x and y from its formula), then either Ksp or molar solubility — leave the other blank to solve for it. For example, Mg(OH)₂ has x=1, y=2, since it dissociates into 1 Mg²⁺ and 2 OH⁻.
