WebFor example, if you prepare a Tris buffer at pH 7.0 at 4.0°C and perform a reaction in that same buffer at 37°C, the pH will drop to 5.95. If you have a Tris buffer prepared at 20°C with a pK a of 8.3, it would be an effective buffer for many biochemical reactions (pH 7.3–9.3), but the same Tris buffer used at 4°C becomes a poor buffer at ... WebJan 30, 2024 · Human blood contains a buffer of carbonic acid ( H 2 CO 3) and bicarbonate anion ( HCO 3 −) in order to maintain blood pH between 7.35 and 7.45, as a value higher than 7.8 or lower than 6.8 can lead to death.
