Question

What is the ph of a solution containing 0.01 m acetic acid (pka = 4.7) and 0.1 m sodium acetate?

Answer 1

The ph of a solution is 3.7

Solution:

According to the equaiton of Henderson-Hasselback

      pH= pKa+ log(salt/acid)

here it is given the value of

      pKa= 4.7

So,

      pH = pKa+ log(0.1/0.01)

            = 4.7 + log(0.1)

            = 4.7–1

            = 3.7.

The following problem illustrates how the Henderson-Hasselbalch equation can be used to determine how much acid and conjugate base should be combined to create a buffer solution with a specific pH.
