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?
