1. Principle
A buffer solution is an aqueous solution consisting of a mixture of a weak acid and its conjugate base or a weak base and its conjugate acid. It has the property that the pH of the solution changes very little when a small amount of strong acid or base is added to it. Buffer solutions are used as a means of keeping pH at a nearly constant value in a wide variety of chemical applications.
Buffer solutions are used to maintain a certain level on the pH scale.
Good buffer solutions is pH ≈ pKa.
The acid dissociation constant for a weak acid, HA, is defined as
