Question Answered step-by-step * I know that the answer is D because if a reaction proceeds… * I know that the answer is D because if a reaction proceeds towards the reactants, then the Ca ion concentration will decrease. But how does adding NaF to the solution cause this? CaF2(s) ?? Ca 2+(aq) + 2 F ?(aq) ?H> 0Dissolution 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 CaF 2(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 Science Chemistry CHM 2210 Share QuestionEmailCopy link Comments (0)
