SUMMARY
The discussion centers on the preparation of a buffer solution using 0.30M acetic acid and 0.10M sodium acetate, followed by the addition of 100mL of 0.10M HNO3. The equilibrium reaction indicates that both CH3COO- and H+ reach a molarity of zero, leading to the conclusion that the acetic acid and sodium nitrate are the predominant species in the solution. The equilibrium constant (Ka) for acetic acid is 1.8 x 10-5, which is crucial for understanding the buffer's behavior under acidic conditions.
