Solve the following problem: MgF2(s)⇌Mg2+(aq)+2F−(aq)MgF2(s)⇌Mg2+(aq)+2F−(aq) In a saturated solution of MgF2at 18 °C, the concentration of Mg2+is 1.21××10–3M. The equilibrium is represented by the preceding equation. (a) Write the expression for the solubility-product constant,Ksp, and calculate its value at 18 °C. (b) Calculate the equilibrium concentration of Mg2+in 1.000 L of saturated MgF2solution at 18 °C to which 0.100 mol of solid KF has been added. The KF dissolves completely. Assume the volume change is negligible. (c) Predict whether a precipitate of MgF2will form when 100.0 mL of a 3.00××10–3-Msolution of Mg(NO3)2is mixed with 200.0 mL of a 2.00××10–3-Msolution of NaF at 18 °C. Show the calculations to support your prediction. (d) At 27 °C the concentration of Mg2+in a saturated solution of MgF2is 1.17××10–3M. Is the dissolving of MgF2in water an endothermic or an exothermic process? Give an explanation to support your conclusion.
