Consider the reaction Cu2+(aq) + 4 NH3(aq) 
Cu(NH3) 42+(aq)
Kf = 2.1 × 1013
If the Ksp for Cu(OH) 2 is 2.2 × 10-20,what is the value of the equilibrium constant,K,for the reaction below?
Cu(NH3) 42+(aq) + 2 OH-(aq) 
Cu(OH) 2(s) + 4 NH3(aq)
A) 1.0 × 10-33
B) 4.6 × 10-7
C) 2.1 × 1013
D) 2.2 × 106
E) 9.5 × 1032
