If Cu(OH)2 has Ksp = 1.6 x 10−19, what is the molar solubility of Cu(OH)2?
a) 5.1 × 10−10 M
b) 6.4 × 10−7 M
c) 2.7 × 10−11 M
d) 1.7 × 10−10 M
e) 3.4 × 10−7 M
the Ksp of the Cu(OH)2 is as follows
Cu(OH)2 ---------------------> Cu2+ + 2 OH-
I 0 0
C x 2x
Ksp = [Cu2+] [OH-]2
Ksp = (x)(2x)2
Ksp = 4x3
=> 1.6*10-19 = 4x3
=> x = 3.4199*10-7 M = molar solubility
answer => e = 3.4*10-7 M

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.
