WebBuffer capacity is defined as the number of moles of acid or base that have to be added to 1 liter to cause its pH to change by 1 unit. As a formula this is: B = n/ΔpH, where B is buffer capacity (which is unitless), n is the number of moles of acid or base that was added to the buffer per liter of the buffer, and ΔpH is the pH difference between the initial buffer’s pH … WebA buffer is a solution that is resistant to pH when small quantities of an acid or a base are added to it. Buffers consist of a weak conjugate acid-base pair. This means it's either composed of a weak acid and its conjugate base, or a weak base and its conjugate acid. However, this depends on the desired pH.
