Question: one liter 1l of 01 m tris buffer pka83 is...

Question details

One liter (1L) of 0.1 M Tris buffer (pKa=8.3) is prepared and adjusted to pH 6.2. Using the Henderson-Hasselbalch equation, you find that the ratio of conjugate base to weak acid is [A-]/[HA]=0.79/1 From this, you calculate the following concentrations: [A-]=0.034 M and [HA]=0.076 If you add 1.5 mL of 3 M HCL to 1 L of this buffer, what are the new concentrations of [A-] and [HA]? What is the new pH? Did the buffer work?
