A buffer system is designed using acetic acid, CH3COOH, and sodium acetate, NaCH3COO. The pKaof acetic acid is 4.74.

a)What is the pH of a buffer solution containing 0.14 M of CH3COOH and 0.18 M of NaCH3COO?

b)What is the pH of a buffer solution containing 0.11 M of CH3COOH and 0.04 M of NaCH3COO?c)Which of the buffer systems from a) or b) above is better able to maintain a steady pH on the addition of small amounts of either a strong acid or a strong base?Explain.
