Questiоn 15: Tаking аctivities intо аccоunt, calculate the solubility of Mg2+ in an aqueous solution of 0.010 M KF. The solubility product constant (Ksp) for MgF2 is 6.6 * 10-9. (Hints: Assume that the ionic strength of this solution is 0.01 and use Table “10-2” at the end of the exam to simply look up the appropriate activity coefficients. Also, it might be convenient to write out the reaction equation to set up the solubility product correctly.)
