Calcium fluoride, CaF2, is an insoluble salt (Ksp = 1.46 x 10-10)
that can be formed by precipitation by mixing solutions of
calcium nitrate and sodium fluoride. Suppose 200.0 mL of a
0.600 M Ca(NO3)2(aq) solution are mixed with 400.0 mL of a
0.0600 M NaF(aq) solution. Will a precipitate form? How much
calcium fluoride could form?

A solution containing sodium fluoride is mixed with one containing calcium nitrate to form a solution that is 0.015 M in NaF and 0.010 M in Ca(NO3)2 Will a precipitate form in the mixed solution? If so, identify the precipitate. Express your answer as a chemical formula. Enter noreaction if no precipitate is formed. Submit Request Answer
Calcium fluoride (CaF2) has a Ksp of 3.45∙10-11. If I have a 0.150 M solution of sodium fluoride, what concentration of calcium acetate will begin precipitation of the fluoride ions?
6.) (8) The Ksp for Calcium Fluoride is 1.46 x 10-10. How many milligrams of Ca2+(aq) can be present in 3.75 L of 0.25M NaF solution? (Molar mass of Ca = 40.08 g/mol) Final answer:
17. Calculate the solubility of calcium fluoride in a 0.035 M sodium fluoride solution. Some important information is given below: ▪ NaF will ionize completely, and the reaction is: NaF (aq) → Na+ (aq) + F− (aq) ▪ The calcium fluoride equilibrium reaction is: CaF2 (s) → Ca+2 (aq) + 2F−1 (aq) ▪ For CaF2 (s), Ksp is 4.0 × 10−11 ▪ Na+ (aq) is a spectator ion; The F− (aq) is the common ion.

Calculate the molar solubility of CaF2 in a solution containing 0.647 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.
The Ksp of barium fluoride is 1.00 x 10–6. The Ksp of calcium fluoride is 3.90 x 10–11. An aqueous solution of sodium fluoride is slowly added to a water sample that contains barium ion (3.00×10-2M ) and calcium ion (5.95×10-2M ). What is the remaining concentration of the first ion to precipitate when the second ion begins to precipitate?
