Web7 years ago. Yes, the pH of the blood is controlled by the bicarbonate buffer system: CO₂ (g) + H₂O (l) ⇌ H₂CO₃ (aq) ⇌ H⁺ (aq) + HCO₃⁻ (aq) If the concentration of CO₂ temporarily gets too high, the ability of the buffer to control pH may be temporarily overloaded. Fortunately, too much CO₂ in the blood triggers a reflex ... WebApr 1, 2024 · What Is the Purpose of a Buffer in Chemistry? Buffer solutions play a large role in biochemical functions. Because buffers resist changes in pH levels, they are used to regulate biological functions that only occur at certain pH levels. Buffers can also be used to store compounds that would denature in more acidic or basic solutions. A buffer ...
