The formula to calculate the molar solubility is:
\[ \text{S} = \sqrt{\frac{\text{Ksp}}{a \times b}} \]
Where:
Let's consider an example:
Using the formula to calculate the molar solubility:
\[ \text{S} = \sqrt{\frac{1.0 \times 10^{-10}}{1 \times 1}} = \sqrt{1.0 \times 10^{-10}} = 1.0 \times 10^{-5} \text{ mol/L} \]
This demonstrates that with a Ksp of 1.0 x 10^-10 and coefficients of 1 for both ions, the molar solubility is 1.0 x 10^-5 mol/L. ✅
