WebOct 19, 2023 · So, to give a more clear definition, buffer capacity may be defined as the quantity of a strong acid or strong base that must be added to one liter of a solution to change it by one pH unit. The buffer capacity equation is as follows: where n is some equivalents of added strong base (per 1 L of the solution).

Weba year ago. Buffer 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 ...

WebBuffer capacity is a property of a buffer and it tells you how much acid or base you can add before the pH starts changing. Basically, as your buffer capacity goes up, which I'm going to abbreviate BC, as your buffer capacity goes up, you can add more of your acid or base before the pH starts changing a lot.
