13. Z²+ can form a hexaammonia complex ion in the presence of ammonia (K₁ = 1.3 x 105). Z³+ can also form a hexaammonia complex ion in the presence of ammonia (Kf = 2.3 x 102³). ZCl₂ has a Ksp value of 1.8 x108. ZCl3 has a Ksp value of 2.7 x 10-¹². Z is a transition metal. a. Which compound would be more soluble in an 0.100 M NH3 solution ZCl3 or ZCl₂? b. Calculate the molar solubility of ZCl3 in pure water. c. NH₂(CH3) is a better ligand with Z3+ than NH3. Would this increase or decrease the solubility of ZCl3 if the 0.100 M NH3 solution was replaced with a 0.100 M NH₂(CH3) solution (provided NH2(CH3) can also form a hexamine complex ion with Z³+)?
