Question

buffers
are strong acids or bases.
keep the ph within normal limits.
lower the ph.
release large amounts of hydrogen ions (h⁺).

Explanation:

Buffers are solutions that resist changes in pH by neutralizing added acids or bases, thus maintaining pH within a stable, normal range. They are not strong acids/bases, do not inherently lower pH, and do not release large amounts of H⁺; instead, they either accept or donate H⁺ as needed to stabilize pH.

Answer:

keep the pH within normal limits.
