question
which statement about buffers is true?
select all that apply
buffers neutralize solutions donating hydrogen ions or accepting hydrogen ions.
buffers are composed of a strong acid and a strong base.
buffers help maintain homeostasis.
buffers prevent large changes in ph.

Explanation:

Buffers are solutions that resist changes in pH upon addition of small amounts of acid or base. They work by donating or accepting hydrogen ions. They are typically composed of a weak - acid and its conjugate base or a weak - base and its conjugate acid, not a strong acid and strong base. Buffers help maintain homeostasis in biological systems by preventing large changes in pH.

Answer:

A. Buffers neutralize solutions donating hydrogen ions or accepting hydrogen ions.
C. Buffers help maintain homeostasis.
D. Buffers prevent large changes in pH.
