Tris is a common buffering agent and is short for tris[hydroxymethyl]aminomethane.

  • The pKa of Tris is 8.3
  • dpKa/dT is -.028
  • A buffer at pH 6.8 at 25C will have a pH of 6.46 at 37C
    • Note that adding HCl during titration will affect the temperature of the solution
  • Dilution by a factor of 10 will reduce the pH by 0.1 pH units.
