Ksp = 2.6×10-9 for SrF2 at 25 °C.
a. Calculate the molar concentration of fluoride ions in a saturated strontium fluoride solution at 25 °C using the assumption that the solution is ideal -- i.e. the activity coefficients are 1.
b. Using activity coefficients determine the molar solubility of SrF2 in 0.100-M potassium nitrate solution at 25 °C?
c. Using activity coefficients calculate the maximum mass of SrF2 which can dissolve in 100. mL of 0.100 M KF?
