The molar solubility of CaF2 (s) in a saturated solution can be increased by adding:a.) CaCl2 b.)NaF c.)HBr d.) None of the aboveThe answer is HBr, why? Is it because of the increase in H+? Please help. Thanks!!
a) The molar solubility of calcium fluoride, CaF2, is 2.1 × 10-4 mol L-1. From this we can calculate the Ksp of CaF2 to bea) 9.3 × 10-12.b) 1.9 × 10-11.c) 3.7 × 10-11.d) 8.8 × 10-8.b)What is the molar solubility of calcium fluoride, CaF2 (Ksp = 3.9 × 10-11 ), in a 0.10M sodium fl...
