Enter the concentration and solubility of a solute into the calculator to determine the solubility constant (Ksp). This calculator helps in understanding the solubility equilibrium of a solute in a solution.
Solubility Constant Formula
The following formula is used to calculate the solubility constant (Ksp).
Ksp = S^2 / C
Variables:
- Ksp is the solubility constant
- S is the solubility of the solute (mol/L)
- C is the concentration of the solute (mol/L)
To calculate the solubility constant, divide the square of the solubility (S) by the concentration (C).
What is a Solubility Constant?
The solubility constant, also known as the product of solubility equilibrium constant (Ksp), is a value that represents the level at which a solute dissolves in a solution at equilibrium. It is a constant for a given substance at a specific temperature and is used to predict the solubility of the substance in a solvent. The Ksp is particularly useful for predicting the formation of precipitates and understanding the solubility of sparingly soluble salts.
How to Calculate Solubility Constant?
The following steps outline how to calculate the Solubility Constant (Ksp).
- First, determine the solubility of the solute (S) in mol/L.
- Next, determine the concentration of the solute (C) in mol/L.
- Use the formula Ksp = S^2 / C to calculate the solubility constant.
- Finally, enter the values into the calculator to verify the solubility constant (Ksp).
Example Problem :
Use the following variables as an example problem to test your knowledge.
solubility of the solute (S) = 0.01 mol/L
concentration of the solute (C) = 0.05 mol/L
