Uses of Buffer Solutions

Various uses of Buffer solution are,

  • Buffer solutions are referred to by several different names, including pH buffers and hydrogen ion buffers.
  • Many organisms employ buffer solutions to maintain an optimum pH for enzyme activity.
  • The use of bicarbonate and carbonic acid buffer system to manage the pH of animal blood is an example of a buffer used in pH regulation.
  • Enzyme function may be hindered, features may be lost, or the enzymes may even denature if certain buffers are not present. The enzymes’ catalytic function can be completely deactivated by this denaturation process.

Buffer Solution

Buffer Solution is a special aqueous solution that resists the change in its pH when some quantity of acid and Base is added. Many fluids, such as blood, have specific pH values of 7.14, and variations in these values indicate that the body is malfunctioning.  The change in pH of Buffer Solutions on adding a small quantity of acid or bases is very minimal and hence they are used to make solutions that resist the change in pH.

Buffer Solution Definition

A buffer solution is a solution that resists changes in hydrogen ion concentration when a modest amount of acid or base is added. In other words, such solutions are known to have reverse acidity and reverse basicity and to keep a reasonably steady pH value. A good example of a natural buffer solution is human blood. Despite eating a wide array of meals, our blood maintains a pH of roughly 7.35....

Mechanism of Buffering Action

To understand how a buffer works, think about the example of a buffer solution created by combining sodium acetate and acetic acid. Acetate acid, as implied by its name, is an acid with the chemical formula CH3COOH, whereas sodium acetate dissociates in solution to produce the conjugate base CH3COO– acetate ions. The reaction equation is:...

Preparation of Buffer Solution

A buffer solution can be made by controlling the salt acid or salt base ratio if the dissociation constants of the acid (pKa) and the base (pKb) are known. Weak bases and their conjugate acids, or weak acids and their respective conjugate bases, are used to make these solutions. The Handerson-Hasselbalch equation and the preparation of acidic buffer and basic buffer....
