Answer :
From the calculations carried out , we can see that the molar solubility of Al(OH)3 is 8.6 x 10^-12 M
What is solubility?
The term solubility refers to the amount of substance that dissolves in a solution measured in moles per liter.
From the question we have initial [Al+3] = 0.05 M
Setting up an ICE table:
Al(OH)3(s) → Al3+ + 3OH-
I 0.05 0
C +x +3x
E 0.05+x 3x
Know that;
Ksp = [Al3+] [OH-]^3
Ksp = 1.3 x 10^-33
So;
[Al3+] = (0.05+X) and [OH-]^3 = 3X
If x = molar solubility of Al(OH)3
Then:
1.3 x 10^-33 = (0.05 + X) (3X)^3 by solving for X
x = 8.6 X 10^-12 M
