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 … WebMar 15, 2013 · In addition, it should be mentioned that the interactions of ions with acid–base groups of proteins also affect their buffering capacities.
