Gce Model Questions Vol1 2017 Chemistry Question 1
Practice objective / multiple choice question 1 from the 2017 Gce Model Questions Vol1 Chemistry examination.
A buffer solution is prepared by dissolving 0.20 mol of acetic acid (CH₃COOH) and 0.15 mol of sodium acetate (CH₃COONa) in enough water to make 1.00 L of solution. After the buffer is prepared, 0.05 mol of hydrochloric acid (HCl) is added. Assuming the volume change is negligible, calculate the pH of the solution after the addition of HCl. (Ka of acetic acid = 1.8 \times 10⁻⁵).
