(TRIS BUFFERS). the acid dissociation constant for TRIS is 8.32 x 10^-9. Considering the TRIS HCL as the acid "HA" and TRIS as the "anion" "A" , calculate the pH of the 1 L solution of 0.25 M TRIS plus the addition of 0.05 M HCL. Show how many moles of TRIS and TRIS HCL are present after the addition of the HCL. Use the Henderson Hasselbalch equation to calculate the pH?
