Tris base molarity

WebThe pKa of Tris is 8.1, which means that at pH 8.1, the buffer system is half protonated and half deprotonated. The Henderson-Hasselbalch equation is: pH = pKa + log([A-]/[HA]) where pH is the desired pH, pKa is the dissociation constant of the buffer, [A-] is the concentration of the conjugate base, and [HA] is the concentration of the weak acid. WebAnd since molarity is the ratio of the number of moles of a solute by the volume of the solution, if you double to the volume, double the numerator, you half the overall ratio …
