An aqueous solution of sodium fluoride is slowly added to a water sample that contains barium ion (4.65x10-2 M)
An aqueous solution of sodium fluoride is slowly added to a water sample that contains barium ion (4.65x10-2 M) and calcium ion (7.40x10-2 M).The Ksp of barium fluoride is 1.00x10-6. The Ksp of calcium fluoride is 3.90x10-11. What is the remaining concentration of the first ion to precipitate when the second ion begins to precipitate?
