A solution of 0.1 L of 0.3 M Ca(NO3)2 is mixed with 0.2 L of 0.06 M NaF. Calculate the reaction quotient Qsp. Does calcium fluoride precipitate? (Ksp (CaF2) = 3.2×10–11). (A) Qsp = 1.6×10–4; no precipitate. (B) Qsp = 1.6×10–4; a precipitate will form. (C) Qsp = 3.2×10–11; no precipitate. (D) Qsp = 3.2×10–11; a precipitate will form. (E) Qsp = 3.2×10–7; no precipitate.
A solution containing 0.3M of HF also contains 0.02 M Ca(NO3)2. HCl is added slowly until the solution has a pH of 2.00. Will a precipitate of CaF2 occur? For the HF, Ka = 6.46x10-4 and for the CaF2, Ksp = 2.69x10-11
QUESTION 3 A solution is prepared by mixing 30.0 mL of 0.60 M Ba(NO3)2 and 30.0 mL of 0.60 M Ca(NO3)2. Sodium fluoride is added to the mixture. Assume there is no volume change from the addition of sodium fluoride. Which compound precipitates first and at what concentration of F will we first see the precipitate form? Ksp BaF2 = 1.8 x 107 and Ksp CaF2 = 1.5 x 10-10 1. BaF2; 3.6 × 10-3M 2. CaF2; 7.2 10-4 M...
