Question

A buffered solution contained dissolved aniline C6H5NH2 and aniline hydrochloride C6H5NH3Cl, has a pH of 5.66. Determine the concentration of C6H5NH3+ in the solution if the concentration of C6H5NH2 is 0.230 M. The pKb of aniline is 9.13. The concentration of C6H5NH3+ is 0.03730 M. B. Calculate the change in pH of the solution (ΔpH) if 0.360 g NaOH is added to the buffer for a final volume of 1.35 L. Assume that any contribution of NaOH to the volume is negligible.

Step 1

We can use the Henderson-Hasselbalch equation for this: pH = pKa + log([C6H5NH2]/[C6H5NH3+]) We are given the pH (5.66) and the concentration of C6H5NH2 (0.230 M). We also know that pKa = 14 - pKb, so pKa = 14 - 9.13 = 4.87. Now we can solve for the Show more…

A buffered solution containing dissolved aniline, C6H5NH2, and aniline hydrochloride, C6H5NH3Cl, has a pH of 5.59. a) Determine the concentration of C6H5NH3 in the solution if the concentration of C6H5NH2 is 0.200 M. The pKb of aniline is 9.13. b) Calculate the change in pH of the solution, ΔpH, if 0.397 g NaOH is added to the buffer for a final volume of 1.10 L. Assume that any contribution of NaOH to the volume is negligible. I'm stuck on the part b, if all the steps to part b can be posted that would help a lot!
