Carbonic acid (H 2 CO 3) is a weak acid and is therefore in equilibrium with bicarbonate (HCO 3-) in solution. When significant amounts of both carbonic acid and bicarbonate are present, a buffer is formed. This is the isohydric principle. Because of this link, adjustment of the bicarbonate buffer system controls all buffer systems. The bicarbonate buffer system has two components: plasma [CO 2] and [HCO 3 −]. The respiratory system controls plasma pH by adjusting the [CO 2]; the renal system adjusts [HCO 3 −]. The bicarbonate buffer is the primary buffering system of the IF surrounding the cells in tissues throughout the body. The respiratory and renal systems also play major roles in acid-base homeostasis by removing CO 2 and hydrogen ions, respectively, from the body.

By increasing the partial pressure of carbon dioxide, the pH of blood will fall and turn acidic. The usual range of blood pH is from 7.35 to 7.45. When pH levels drop below 7.35, it is said to be acidotic, and when pH levels rise above 7.45 it is said to be alkalotic. The carbonic acid bicarbonate buffer system is made up of carbonic acid. They are weak acids, and their conjugate base is bicarbonate anion. Phosphate buffer ...Principally by the bicarbonate buffer system (the non-bicarbonate buffer systems play a greater role in buffering the acidosis resulting from bicarbonate depletion).

RBC buffering: The positively charged hydrogen ions enter RBC.Jul 13, 2023 · If you understand the Henderson-Hasselbalch equation from the previous section, buffer systems become easy to understand. pH = pKa + log [A−] HA (2.3.1) (2.3.1) p H = p K a + log [ A −] H A. At the inflection point of the curve, pH = pKa and the system is most resistant to changes in pH on the addition of either acid or base. Thus, the pK a for NH 4 + = 9.25, so buffers using NH 4 + /NH 3 will work best around a pH of 9.25. (It's always the pK a of the conjugate acid that determines the approximate pH for a buffer system, though this is dependent on the pK b of the conjugate base, obviously.)
