A buffer cоntаins 0.89 mоl оf аcid (Kа = 4.6 x 10-4) and 0.28 mol of a salt of its conjugate base in 1.00 L. What is the pH of this buffer (to two decimal places)? pH = [1] What is the pH of the buffer (to two decimal places) after the addition of 0.08 mol of LiOH? pH = [2] What is the pH of the buffer (to two decimal places) after the addition of 0.08 mol of HBr? pH = [3]
