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...

Explain the relationship between the average moles of strong acid that must be added to change the pH of 25 mL of each buffer by one pH unit and the [Conj. base]/[Weak acid] ratio for the buffer. (What happens to the average number of moles of strong acid that must be added when the [Conj. base]/[Weak acid] ratio decreases? Why does the average number of moles of strong acid change as it does?)
