a. Using the Ksp value for Cu(OH)2 (1.6 x 10-19) and the overall formation constant for Cu(NH3)42+ (1.0 x 1013), calculate the value for the equilibrium constant for the following reaction: Cu(OH)2 (s) + 4NH3 (aq) ⇌ Cu(NH3)42+(aq) + 2OH -(aq) b. Use the value of the equilibrium constant you calculated in part a to calculate the solubility (in mol/L) of Cu(OH)2 in 5.0 M NH3. In 5.0 M NH3 the concentration of OH - is 0.0095 M.
What is the molar solubility of AgCl (Ksp = 1.80 x 10-10) in 0.330 M NH3? (Kf of Ag(NH3)2* is 1 x 107) IM What is the equilibrium constant for the solubility of FeCO3 (Ksp = 2.1 x 10-11) in NaCN? (Kf of Fe(CN)64-is 1.0 x 1035)
The Ksp of Cd(OH)2 is 5.9x10^-15 and the Kf of Cd(NH3)4^2+ is 1.0x10^7. Use these values to determine if Cd(OH)2 precipitate will form in a solution made by mixing 1.0 mL of 1.0M aqueous Cd(NO3)2 with 1.0 L of 5.0M aqueous NH3. The Kb for ammonia is 1.8x10^-5 Kf if K of formation. This is not given info. we’ re supposed to know this for this problem

H. Complex Ions 1. Silver chloride has very low solubility in water (Ks of 1.6 x 10-19), however, it is highly soluble in an ammonia solution due to the formation of the complex ion [Ag(NH3)21 (Kr" 1.7 X 10) Given this information, calculate the molar solubility of AgCl in 2.25 M ammonia. 2. Calculate the molar solubility of Cul in 0.92 M KCN. (Ksp of Cul is 1.1 x 10-12, Kp of [Cu(CN)2] is 1.0 x 1016).
