Applications:
 
TRIS has a pKa of 8.07 at 25 °C, which implies that the buffer has an effective pH range between 7.07 
and 9.07. It can be used as acidic gas absorption agent; Titration acid quantity/ material; Current titration 
in the determination of protein sulfhydryl group; Paper serum protein electrophoresis separation and 
Starch electrophoresis separation of toxins. It also can be used to make surfactants synthesis, 
pharmaceutical intermediates, chemical intermediates, organic synthesize intermediates.
