Buffer Capacity Calculator

Buffer capacity, you need to divide the number of moles of the acid/base



Buffer Capacity


  • β = Buffer capacity
  • n = Number of moles of an acid
  • ΔpH = final pH - initial pH

Defination / Uses

A buffer is a solution which is resistant to pH variations. A weak acid, its salt, and a strong base, or a weak base, its salt, and a strong acid, make up this compound. Food items, medications, cosmetics, and pharmaceuticals all require buffers to keep their pH in control.

In our blood's pH is kept between 7.35 and 7.45 by blood buffers! The resistance of a buffer solution to pH changes after the addition of OH- or H+ is determined by buffer capacity. The pH change after adding an acid or base is influenced by the buffer's capacity and starting pH. Use the upper given formula for manual calculations.
