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 ...

Influences on dissociation: There should be a minimum influence of buffer concentration, temperature, and ionic composition of the medium on the dissociation of the buffer. Well-behaved cation interactions: If the buffers form complexes with cationic ligands, the complexes formed should remain soluble. Ideally, at least some of the buffering ...
It is these traits that have scientists so fixated on extremophiles because the genes that allow for said abilities can be taken from extremophiles and used in various biotechnical processes. A good example of this would be how Taq Polymerase was isolated from the bacteria Thermus aquaticus and was then used to make the process of PCR possible. [5]
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.
The conjugate bases of organic acids such as citrate and lactate are often used in biologically compatible buffer solutions. Citric and oxalic acids are used as rust removal. As acids, they can dissolve the iron oxides, but without damaging the base metal as do stronger mineral acids.
Research by academics carried out in Poland suggests that higher levels of resilience improve life satisfaction and act as a buffer against mental health problems among young people.
Tris-buffered saline (TBS) is a buffer used in some biochemical techniques to maintain the pH within a relatively narrow range. Tris (with HCl) has a slightly alkaline buffering capacity in the 7–9.2 range. The conjugate acid of Tris has a pK a of 8.07 at 25 °C. The pK a declines approximately 0.03 units per degree Celsius rise in ...
