Tris Buffer
Tris buffer, chemically known as Tris(hydroxymethyl)aminomethane or Trometamol, is a critical zwitterionic biological buffer. Its primary utility lies in its ability to resist changes in pH when acids or bases are added, making it indispensable for maintaining stable conditions in a myriad of biological and chemical processes. With a pKa of 8.07 at 25°C, Tris buffer is particularly effective in the pH range of 7.0 to 9.0, a range that closely aligns with the physiological pH of most living organisms.
