When Are Buffers Used?

It is used to prevent any change in the pH of a solution, regardless of solute. Buffer solutions are used as a means of keeping pH at a nearly constant value in a wide variety of chemical applications. For example, blood in the human body is a buffer solution.

Where are buffer used?

Buffers are used to run biochemical assays. For example, enzyme activity varies with pH, so you have to keep the pH constant to get accurate results. Buffer solutions are used in medicines that require a constant pH.

How are buffers used in real life?

The body uses buffers solution to maintain a constant pH. For example, blood contains a carbonate/bicarbonate buffer that keeps the pH close to 7.4. Enzyme activity depends on pH, so the pH during an enzyme assay must stay constant. In shampoos.
