SUMMARY
The discussion focuses on calculating the pH of a solution created by mixing 200 mL of 0.2 M acetic acid (CH3COOH) with 100 mL of 0.1 M sodium hydroxide (NaOH). The relevant equilibrium reaction is CH3COOH + NaOH ⇔ NaCH3OO + H2O, with the acid dissociation constant (Ka) given as 1.8 x 10^-5. Participants emphasize the importance of applying the Henderson-Hasselbalch equation and understanding the equilibrium concentrations to determine the final pH accurately.
