The complex ion Cu(NH3)42 is formed in a solution made of 0.0300 M Cu(NO3)2 and 0.400 M NH3. What are the concentrations of Cu2 , NH3, and Cu(NH3)42 at equilibrium? The formation constant*, Kf, of Cu(NH3)42 is 1.70 × 1013. This is what the hint gave me, Since the formation constant, Kf, is very large, it can be assumed that the reaction goes nearly to completion to form Cu(NH3)42 . Cu2 is the limiting reagent and will be used up...
