Please answer Questions 3 & 4 with the info given on the first page.
What is the pH at the equivalence point? What is the pH when 25.0 mL of 1.00 M NaOH has been added? Lactic acid, HC_3H_5O_3 (see right for structure), builds up in muscles after vigorous exercise. It is a weak acid with a pK_a = 3.86. Consider the following titration: 25.0 mL 0.500 M lactic acid is titrated with 1.00 M NaOH. Answer the following questions. What is the pH of the lactic acid solution before any NaOH is added? What is the pH after 5.00 mL of 1.00 M NaOH is added?
