Pyruvic acid (HC3H3O3) is an acid in our bodies that supplies energy to our cells through the citric acid cycle. A solution containing pyruvic acid (5.00 mL, 0.250 M) is titrated with standard sodium hydroxide (0.150 M). What is the pH in the titration flask after addition of 20.00 mL of the standard solution of sodium hydroxide? pKa = 2.387 for pyruvic acid. Hint: Assume that the volumes of the solutions are additive.
