1.) What is the maximum concentration of Mg2+ion that can remain dissolved in a solution that contains 0.6418 M NH3 and 0.3482 MNH4Cl? Ksp for Mg(OH)2 is 1.5 × 10-11. Kb for NH3 is 1.8 × 10-5. Answer in units of M.

2.) Remember that Kd is the reverse of Kf. In a 0.20 M solution of the saltCu(NH3)4SO4, the concentration of Cu2+ ion is found to be 9.21 × 10-4 M. What is the dissociation constant of Cu(NH3)+24?
