Calculate Solubility Constant



Formula

The formula to calculate the Solubility Constant (Ksp) is:

\[ \text{Ksp} = \frac{S^2}{C} \]

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.

Example Calculation

Let's assume the following values:

Using the formula:

\[ \text{Ksp} = \frac{(0.02)^2}{0.1} = \frac{0.0004}{0.1} = 0.004 \]

The Solubility Constant (Ksp) is 0.004.
