bicarbonate buffer solution

A bicarbonate buffer solution helps maintain a stable pH in the body, especially in blood. It consists mainly of bicarbonate ions (HCO₃⁻) and carbonic acid (H₂CO₃). When the blood becomes too acidic, bicarbonate reacts with excess hydrogen ions to neutralize them. If the blood is too alkaline, carbonic acid releases hydrogen ions to balance the pH. This system acts like a natural pH regulator, quickly adjusting to keep blood conditions safe and constant, which is vital for normal body functions.
