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. WebA pH (little p) of 7 only means neutral water at 25°C, but for other temperatures this means a pH above or below 7. This is due to the changing value of water's self-ionization …
