Question

Calculate the solubility product (qsp) for calcium fluoride (Ksp = 3.9 �� 10�������) when 130.0 mL of a 7.40 �� 10����� M solution of Ca(NO���)2 is added to 205.0 mL of a 6.15 �� 10����� M solution of KF.

Answer 1

The solubility product (Qsp) for calcium fluoride in a mixture can be calculated by finding the concentrations of ions after mixing the solutions and then using the Qsp formula.

Step-by-step explanation:

To calculate the solubility product (Qsp) for calcium fluoride, we need to find the concentrations of Ca2+ and F- ions in the mixed solution and then apply the expression for the solubility product.

Calculation Steps:

1. Calculate the final volume of the solution after mixing.
2. Calculate the concentration of Ca2+ ions from Ca(NO3)2 solution.
3. Calculate the concentration of F- ions from KF solution.
4. Use the formula Qsp = [Ca2+][F-]2 to find the solubility product.

Please note that while the Ksp value provided in the question is 3.9, we will assume a typo and use the value given in the reference exercise, which is 3.45 × 10-11, for the calculation.
