H2co3 buffer
WebCarbonic acid (H _2 2 CO _3 3) is a weak acid (pKa1=6.3, pKa2=10.3), and is formed when carbon dioxide combines with water in a reaction catalyzed by the enzyme carbonic anhydrase. In solution, carbonic acid is present in equilibrium with the bicarbonate ion via a simple proton transfer reaction. WebDec 22, 2024 · The buffer that maintains the pH of human blood involves carbonic acid (H2CO3), bicarbonate ion (HCO3–), and carbon dioxide (CO2). When bicarbonate ions combine with free hydrogen ions and become carbonic acid, hydrogen ions are removed, moderating pH changes. How does a carbonate buffer system work? How does a buffer …
