Buffer Solutions

Buffer solutions (also known as pH buffers) are resistant to any pH changes from a strong base or acid presence. Buffer solutions allow for the pH to stay at a constant level due an equilibrium balance. These are used in several applications, such as blood in the human body as a buffer solution. You can learn more in our buffer solution guide.

What are the types of Buffer Solutions?

Acid Buffer Solution - this is used when the pH is less than seven and generally comprises a weak acid
Alkaline Buffer Solution - this is used when the pH is over seven and comprises a weak base (Alkaline)

Buffer solutions offer a balanced pH but that doesn’t mean the buffer solutions have a neutral pH. They can balance the solution from external influences that can change the pH levels.
