Salts dissociate when dissolved in water:
PbSO4 -> Pb2+ + SO4 2-
So there are 2 different particles. 1 mol
of PbSO4 produces 1 mol of Pb2+, and 1 mol of SO4 2- (one of each).
Kps = [Pb2+] [SO4 2-]
We will call “s” the molarity of PbSO4
So the molarity of Pb2+ is also “s” (same
number)
And the molarity of SO4 2- is also “s”
(same number)
Kps = s*s = s2
1.82
× 10-8 = s2
So,
in order to find s, we have to make the square root of 1.82 × 10-8, which is: 0,00013491 M
Answer:
pH = 11.7
Explanation:
pOH= -log [OH]=-log[0.05]
=2.3
pOH+pH= 14
pH= 14-2.3= 11.7
