How bicarbonate buffer system works
The bicarbonate buffer system is an acid-base homeostatic mechanism involving the balance of carbonic acid (H2CO3), bicarbonate ion (HCO 3), and carbon dioxide (CO2) in order to maintain pH in the blood and duodenum, among other tissues, to support proper metabolic function. Catalyzed by carbonic … Ver mais In tissue, cellular respiration produces carbon dioxide as a waste product; as one of the primary roles of the cardiovascular system, most of this CO2 is rapidly removed from the tissues by its hydration to bicarbonate ion. … Ver mais The bicarbonate buffer system plays a vital role in other tissues as well. In the human stomach and duodenum, the bicarbonate buffer system serves to both neutralize Ver mais • Nosek, Thomas M. "Section 7/7ch12/7ch12p17". Essentials of Human Physiology.

WebYou can get significant buffering out to about a 100:1 ratio, so most buffer systems will work over a total range of about 4 pH units; they work best, of course, near the middle … WebThe pH scale is often said to range from 0 to 14, and most solutions do fall within this range, although it’s possible to get a pH below 0 or above 14. Anything below 7.0 is acidic, and anything above 7.0 is alkaline, or basic. …
WebBuffers, protein or otherwise, work by consuming small amounts of acid or base added to a solution. For instance, you're constantly producing carbon dioxide, and you burn sugar and other nutrients to produce energy. While you exhale the carbon dioxide eventually, it's in your blood and other body fluids until you do so, and it's acidic. WebSo, a hydrofluoric acid buffer would work best in a buffer range of around pH = 3.18. For the weak base ammonia (NH 3), the value of K b is 1.8x10-5, implying that the K a for the dissociation of its conjugate acid, NH 4 +, is K w /K b =10-14 /1.8x10-5 = 5.6x10-10. Thus, the pK a for NH 4 + = 9.25, so buffers using NH 4 + /NH 3 will work
