Answer : The pH of calcium acetate solution will be 9.38.
Explanation : When calcium acetate dissocates completely in solution to form Calcium(+2) ions and two acetate ions, this gives the acetate ion concentration as (2 X 0.51 M) = 1.02 M
Acetate ion then hydrolyzes as follows;
:
Now, Kb will be = /
= Kw / Ka
= 1 x / 1.8 x
= 5.6 ×
= 2.4 ×
Now, we know , pOH = -log = 4.62
So, the pH = 14 - pOH = 14 - 4.62 = 9.38
