Ksp Calculator from Molar solubility (Molar solubility to Ksp converter)
If the molar solubility of a partially ionizable salt, such as CaF2, BaSO4, CaCO3, etc., is known, we can easily find its Ksp value at a particular temperature.

How to use molar solubility to Ksp calculator?
(a).Enter the molar solubility value in the “Molar Solubility” input field.
This value represents the concentration of the dissolved substance in moles per liter. For example –
if the molar solubility is 1.05 x 10-5 then enter the value in input fields as 1.05e-5
Another example is if the molar solubility is 2.14 x 10-4 then enter the value in input fields as 2.14e-4
(b).Enter the Ratio A value in the “Ratio A” input field.
Ratio A represents the stoichiometric coefficient of the first ion in the chemical equation relative to the dissolved substance.
For example, in CaF2(s) ⇌ Ca2+(aq) + 2F–(aq), the Ratio A for Ca2+ would be 1.
(c).Enter the Ratio B value in the “Ratio B” input field.
Ratio B represents the stoichiometric coefficient of the second ion in the chemical equation relative to the dissolved substance.
In the CaF2 example above, the Ratio B for F– would be 2.
(d).Click the “Calculate Ksp” button to obtain the Ksp value.
The result will be displayed in scientific notation below the button.
Remember to always refer to the balanced chemical equation of the substance to determine the correct stoichiometric coefficients (Ratio A and Ratio B) for each ion involved in the reaction.
Example of calculating Ksp value using “molar solubility to Ksp calculator”
Calculate the Ksp for barium sulfate (BaSO4) from its molar solubility of 1.05 x 10⁻⁵ M at 25°C.
To calculate the Ksp for BaSO4, we first write the balanced chemical equation for the dissolution of barium sulfate:
BaSO4(s) ⇌ Ba²⁺(aq) + SO42-(aq)
Here, Ratio A represents the stoichiometric coefficient of Ba²⁺ relative to BaSO4, which is 1. Ratio B represents the stoichiometric coefficient of SO42- relative to BaSO4, which is also 1.
Using the molar solubility to Ksp calculator, input the following values:
⇒ Molar Solubility: 1.05 x 10-5 as 1.05e-5
⇒ Ratio A: 1
⇒ Ratio B: 1
Click “Calculate Ksp” and obtain the result:
∴ Ksp = 1.102 x 10-10
Determine the Ksp of calcium fluoride (CaF2) given that its molar solubility is 2.14 x 10-4 M at 25°C.
To calculate the Ksp for CaF₂, we first write the balanced chemical equation for the dissolution of CaF2:
Here, Ratio A represents the stoichiometric coefficient of Ca2+ relative to CaF2, which is 1. Ratio B represents the stoichiometric coefficient of F⁻ relative to CaF2, which is 2.
