Acid-base buffer systems minimize pH changes by
A)converting weak acids to strong acids.
B)converting strong acids to weak acids.
C)increasing breathing rate.
D)promoting the excretion of hydrogen ions.

Question

Quizplus · Accepted Answer

Acid-base buffer systems work by converting strong acids to weak acids or weak bases. By doing so, they prevent large changes in pH by absorbing excess hydrogen or hydroxide ions. Choice A is incorrect because converting weak acids to strong acids would only increase acidity and lower the pH. Choice C, increasing breathing rate, is not directly related to the buffer systems and is a response to respiratory acidosis. Choice D, promoting the excretion of hydrogen ions, is a function of the kidneys in the renal system, not the buffer system.
