Caf2 solubility
WebSee Answer Question: Calculate the molar solubility of CaF2 in a solution containing 0.853 M of Ca (NO3)2. The Ksp value for CaF2 is 1.46×10−10. Express the molar solubility to three significant figures and include the appropriate units. Calculate the molar solubility of CaF2 in a solution containing 0.853 M of Ca (NO3)2. WebThe concentration of Ca 2+ in a saturated solution of CaF 2 is 2.15 × 10 –4 M. What is the solubility product of fluorite? Solution According to the stoichiometry of the dissolution equation, the fluoride ion molarity of a CaF 2 solution is equal to twice its calcium ion molarity: [F −] = (2molF − /1molCa2 +) = (2)(2.15 × 10 − 4M) = 4.30 × 10 − 4M
