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.
