Explanation:
It is given that for acetic acid is . And, its value will be calculated as follows.
=
= 4.74
And, according to the Henderson-Hasselbalch equation,
pH =
(1). When [Acetic acid] is ten times greater than [acetate]
This means that
So, pH =
=
= 3.74
(2). When [Acetate] ten times greater than [Acetic acid]
This means that =
pH =
= 5.74
(3). When [acetate] = [acetic acid]
This means that = 1
pH =
= 4.74
