Buffering characteristics:
Tris is a weak base, and its pKa is 8.1 at 25ºC. According to buffering theory, the effective buffering range of Tris buffer is between pH7.0 and 9.2. The pH of Chemicalbook aqueous solution of Tris base is about 10.5. H ydrochloric acid is generally added to adjust the pH value to the desired value to obtain the pH buffer. But at the same time, attention should be paid to the influence of temperature on pKa of Tris.
