WebHCO₃⁻ (aq) + H₂O ⇌ H₃O⁺ (aq) + CO₃²⁻ (aq) CO₂ is always being produced in the cells as part of the normal metabolic process. It enters the blood, where it becomes part of the carbonate-bicarbonate buffer system. The blood travels to the lungs, where the dissolved CO₂ crosses the lung membranes and is exhaled in the breath. WebThe pH of the solution is then calculated to be. pH = 14.00 − pOH = 14.00 − − log ( 9.7 × 10 −4) = 10.99. In this unbuffered solution, addition of the base results in a significant rise in pH (from 4.74 to 10.99) compared with the very slight increase observed for the buffer solution in part (b) (from 4.74 to 4.75). WebJan 30, 2024 · Buffers. A buffer is a solution that can resist pH change upon the addition of an acidic or basic components. It is able to neutralize small amounts of added acid or base, thus maintaining the pH of the solution relatively stable.
