Calculate the change in pH of a 1.00 L of a buffered solution preparing by mixing 0.50 M acetic acid (Ka = 1.8 x 10^-5) and 0.50 M sodium acetate when 0.010 mole of NaOH is added. Compare this pH change with that when the same amount 0.010 mole of NaOH was added to 1.00 L of water. (Remember what we did in class a week ago, the pH will jump from 7 to 12 when that tiny amount of NaOH was added).
