WebThe blood buffers consists of the plasma proteins, hemoglobin, oxy-hemoglobin, bicarbonates and inorganic phosphates. 3. When CO 2 enters the venous blood, the small decrease in pH shifts the ratio of acid to salt in all the buffer pairs. When the ratio is shifted to form more of the acid, cations become available to form additional bicarbonates. WebFeb 27, 2024 · Buffer Action: The property of the solution to resist the changes in its pH value on the addition of small amounts of strong acid or base is known as buffer action. …
