How does a buffer help a solution maintain pH?

A) A buffer can act like a base if pH is acidic, and it can act like an acid if pH is basic.
B) A buffer releases a base to neutralize an acid.
C) A buffer forms both cations and anions to counteract acids.
D) A buffer releases acid to maintain proper pH.

Buffer

A solution or compound that stabilizes the pH of a solution by adding or removing hydrogen ions.

Acidic

Characterized by a low pH, indicating a higher concentration of hydrogen ions, often associated with substances like lemon juice or vinegar.

Basic

Characteristic of substances with a pH greater than 7, often capable of neutralizing acids to form water and salts.
