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.

    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?

    Learning Goal: To learn how to calculate the solubility from Kspand vice versa. Consider the following equilibrium between a solid salt and its dissolved form (ions) in a saturated solution: CaF2(s)⇌Ca2+(aq)+2F−(aq) At equilibrium, the ion concentrations remain constant because the rate of dissolution of solid CaF2 equals the rate of the ion crystallization. The equilibrium constant for the dissolution reaction is Ksp=[Ca2+][F−]2 Ksp is called the solubility product and can be determined experimentally by measuring thesolubility, which is the amount...
