Tris is a primary amino compound that is tert-butylamine in which one hydrogen attached to each methyl group is replaced by a hydroxy group. A compound widely used as a biological buffer substance in the pH range 7--9; pKa = 8.3 at 20 ℃; pKa = 7.82 at 37 ℃.

Tris has a pKa of 8.3 (at 20 °C), which implies that the buffer is effective pH range between 7.0 and 9.2. Being slightly basic, tris forms an effective buffer for slightly basic solutions, which keeps DNA deprotonated and soluble in water.

Choose and prepare a biological buffer based on your pH requirements as well as the pKa, a measure of acid strength that accounts for pH, concentration, and temperature.

Tris buffer has a pKa of approximately 8.1 at 25°C making it a good choice for most biological processes in the pH range of 7-9. Compared to other specialized buffers like HEPES, tris powder is a cost-effective and more robust option.

Tris buffer is a good choice for most biological systems because it has a pKa of approximately 8.1 at 25°C, making it an effective buffer in the range of pH 7–9. This pH range is suitable for the majority of biological processes.

Tris (hydroxymethyl) aminomethane is also known as THAM, with pKa 8.06. Tris (M.W: 121.14) is a white crystalline powder having molecular formula C 4 H 11 NO 3. It forms a clear solution in water. Tris is used as a buffering system in most of the biological experiments.

How much HCl must be added to 0.1 M Tris to give pH 7.8? pKa (Tris) = 8.1. (Tris is tris-hydroxy-amino-methane and generally is the base form, e.g. A-) A- + H+ ↔ HA. 0.1-X X. pH = pKa + log ( [ A-]/ [HA]) 7.8 = 8.1 + log ( [ A-]/ [HA]) log ( [ A-]/ [HA]) = -0.3. [ A-]/ [HA] = 10 -0.3 = 0.5. [ A-] = 0.5 [HA] 0.1-X = 0.5X.
