Question

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 add reacts with the strong base in the buffer to form a salt which, produces few H^+ ions in solution and therefore only a little change in pH.

Explanation / Answer

strong acid be H+
It will react with the conjugate base to form weak acid
Now we know the weak acid is weakly dissociated, it will not cause change like strong acid
This is how base workd

Answer:
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
