WebHowever, they are very likely to react with any added strong base or strong acid. If a strong base is added to a buffer, the weak acid will give up its H + in order to transform the … The pH of a solution containing a buffering agent can only vary within a narrow range, regardless of what else may be present in the solution. In biological systems this is an essential condition for enzymes to function correctly. For example, in human blood a mixture of carbonic acid (H 2CO 3) and bicarbonate (HCO 3) is present in the plasma fraction; this constitutes the major mechanism for maintaining the pH of blood between 7.35 and 7.45. Outside this narrow range (7.40 ± 0.05 pH … croma ghodbunder roadWebHCO₃⁻ (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. buff nft
