CaF₂ (s) Ca2+ (aq) + 2F- (aq) HF(aq) H+(aq) + F- (aq) The dissolution of calcium fluoride is represented by the equilibrium system above at 25°C. The F ion is produced when the weak acid HF dissociates. If solid calcium fluoride is added to equal volumes of the following solutions at 25°C, in which solution will the most calcium fluoride dissolve? Pure distilled water 1 M HNO3(aq) 1 M NaOH(aq) K 3.9 x 10-11 A saturated aqueous CaF₂ solution K=6.8 x 104
