SUMMARY
The discussion focuses on the titration of 50 mL of 0.150 M ethylamine (C2H5NH2) with 0.100 M HCl, specifically calculating the pH at two points: after adding 10 mL more HCl than required and after adding 75% of the required acid. The relevant equations include the Henderson-Hasselbalch equation, pH = pKa + log(base/acid), with a given Ka of 2.34 x 10^-4. The first part of the problem involves limiting reagent calculations, while the second part utilizes the Henderson-Hasselbalch equation for pH determination.
