Question:
Which of the following statements about buffer solutions is true?

A. Buffers maintain a constant pH by neutralizing small amounts of added acid or base.
B. Buffers are important in the chemistry of the human body.
C. Both of these statements are true.



Answer :

Final answer:

Buffers are essential in maintaining a steady pH by counteracting acids or bases, which is crucial for biological systems like the human body.


Explanation:

Buffers are solutions that maintain a relatively constant pH by neutralizing small amounts of added acid or base, making the first statement true. They are critically important in biological systems, including the human body, to retain constant pH conditions, supporting the second statement. Therefore, both of these statements are indeed true.
