The molarity of the buffers exceeds the value of the K a by a factor of at least 100. Example 1. Suppose we needed to make a buffer solution with a pH of 2.11. In the first case, we would try and find a weak acid with a pK a value of 2.11.

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.
