Question 1
Calculate the pH of a buffer solution containing 0.1 M acetic acid and 0.1 M acetate. pKa of acetic acid is 4.76. What will the pH be if you add 0.05 M of an acid?
💡 Hint: Remember to adjust concentrations for both components when an external acid is added.
Question 2
If a buffer solution with a pKa of 7.4 has 0.1 M of its weak acid and a conjugate base concentration of 0.05 M, what is the pH? What happens if you add more base?
💡 Hint: Focus on the impact of changing the concentration of the conjugate base.
