A buffer solution is a solution where the pH does not change significantly on dilution or if an acid or base is added at constant temperature. [1] Its pH changes very little when a small amount of strong acid or base is added to it. Buffer solutions are used as a means of keeping pH at a nearly constant value in a wide variety of chemical ...
The bicarbonate buffer system is an acid-base homeostatic mechanism involving the balance of carbonic acid (H 2 CO 3), bicarbonate ion (HCO − 3 ), and carbon dioxide (CO 2 ) in order to maintain pH in the blood and duodenum , among other tissues, to support proper metabolic function. [ 1 ]
The oceans buffer system is known as the carbonate buffer system. [12] The carbonate buffer system is a series of reactions that uses carbonate as a buffer to convert into bicarbonate. [12] The carbonate buffer reaction helps maintain a constant H+ concentration in the ocean because it consumes hydrogen ions, [13] and thereby maintains a ...
Phosphate-buffered saline (PBS) is a buffer solution (pH ~ 7.4) commonly used in biological research. It is a water-based salt solution containing disodium hydrogen phosphate, sodium chloride and, in some formulations, potassium chloride and potassium dihydrogen phosphate. The buffer helps to maintain a constant pH.

These buffers include the bicarbonate buffer system, the phosphate buffer system, and the protein buffer system. [ 7 ] Respiratory component: The second line of defense is rapid consisting of the control the carbonic acid (H 2 CO 3 ) concentration in the ECF by changing the rate and depth of breathing by hyperventilation or hypoventilation .
Ringer's solution typically contains sodium chloride, potassium chloride, calcium chloride and sodium bicarbonate, with the last used to buffer the pH. Other additions can include chemical fuel sources for cells, including ATP and dextrose , as well as antibiotics and antifungals.
TAE buffer is a buffer solution containing a mixture of Tris base, acetic acid and EDTA. In molecular biology, it is used in agarose electrophoresis typically for the separation of nucleic acids such as DNA and RNA. [1] It is made up of Tris-acetate buffer, usually at pH 8.3, and EDTA, which sequesters divalent cations.
