CaF₂(s) Ca2+ (aq) + 2 F (aq) AH>0 Dissolution of the slightly soluble salt CaF₂ is shown by the equation above. Which of the following changes will decrease [Ca²+] in a saturated solution of CaF2, and why? (Assume that after each change some CaF₂(s) remains in contact with the solution.) (A) Allowing some of the water to evaporate from the solution, because more CaF₂(s) will precipitate (B) Adding 0.1 M HNO3(aq), because some F (aq) ions will become protonated (C) Adding 0.1 M NaNO3(aq), because additional liquid will dilute the solution (D) Adding NaF(s), because the reaction will proceed toward reactants CaF₂(s) Ca2+ (aq) + 2 F (aq) AH>0 Dissolution of the slightly soluble salt CaF₂ is shown by the equation above.
