Question 1
Calculate the pH of a buffer solution containing 0.2 M acetic acid and 0.1 M sodium acetate. Given that the pKa of acetic acid is 4.76.
💡 Hint: Apply the equation carefully, ensuring you watch the concentrations.
Question 2
A buffer solution has an initial pH of 4.50. After adding a strong acid, the pH drops to 4.20. What does this indicate about the buffer's capacity?
💡 Hint: Consider how much acidic neutralization occurs with small changes in pH.
