What is the main property of a buffer solution?
A buffer does not allow any change in pH.
A buffer resists drastic changes in pH upon addition of acid or base.
Buffer solutions have an unlimited capacity to resist pH change.
Upon adding a small amount of a strong acid or strong base, a buffer increases the change in pH to a very large amount

How does a buffer resist change in pH upon addition of a strong acid? The strong acid reacts with the weak base in the buffer to form a weak acid, which produces few H + ions in solution and therefore only a little change in pH. The strong acid reacts with the weak acid in the buffer to form a weak base, which produces few H+ ions in solution and therefore only a little change in pH. The strong acid...
