Carbonic Acid Overview
Carbonic acid (H₂CO₃) is a weak, inorganic acid that plays a crucial role in the carbon cycle and physiological pH regulation. It is formed when carbon dioxide dissolves in water and acts as a buffer in blood plasma through the bicarbonate buffer system. While not typically isolated for industrial use due to its instability, it is a key intermediate in forming bicarbonates and carbonates, essential for beverage carbonation and understanding respiratory physiology.
