http://zso.muszyna.pl/live/aaprocess.php?q=sodium-phosphate-buffer-%EC%A0%9C%EC%A1%B0 WebA simple phosphate buffer is used ubiquitously in biological experiments, as it can be adapted to a variety of pH levels, including isotonic. This wide range is due to phosphoric acid having 3 dissociation constants, (known in chemistry as a triprotic acid) allowing for formulation of buffers near each of the pH levels of 2.15, 6.86, or 12.32.
