Decomposition of Carbonic Acid

H2CO3 → H2O + CO2

Tổng quan

Carbonic acid readily decomposes into water and carbon dioxide gas. This unstable acid exists in equilibrium with dissolved CO2 in water. The enzyme carbonic anhydrase catalyzes this reaction in blood, facilitating CO2 transport and release in the lungs.
