When the Carbonic Acid-Sodium Bicarbonate Buffer Pair Buffers an Acid

Question

When the carbonic acid-sodium bicarbonate buffer pair buffers an acid
A) water is an end product
B) carbonic anhydrase reacts with the carbonic acid
C) more sodium bicarbonate is formed
D) more carbonic acid is formed

Accepted Answer

When the carbonic acid-sodium bicarbonate buffer pair buffers an acid, more carbonic acid is formed. This is because the bicarbonate ions react with the hydrogen ions from the acid to form carbonic acid, which maintains the pH within a narrow range.
