A buffer solution is made such that the initial concentrations of lactic acid (HC3H5O3) and the lactate ion (C3H5O3-) are 0.600 M and 0.620 M, respectively. What is the resulting pH if 100.0 mL of 0.100 M potassium hydroxide is added to 0.500 L of the buffer solution? (The Ka of HC3H5O3 is 1.4 x 10-4.) a. 3.81

Question: Lactic acid is a weak acid with the formula HC3H5O3, the ka for lactic acid is 1.38 x 10-4 In aqueous solution, lactic acid partially dissociates according to the following reaction: HC3H5O3 + H20 # C3H5O3 + H30+ Calculate the pH of the lactic acid solution described below: Volume: 400 ml Concentration: 0.1655 M Since this is a weak acid, you can assume the

A buffer solution is made such that the initial concentrations of lactic acid (HC3H5O3) and the lactate ion (C3H5O3-) are both 0.600 M. (The Ka of HC3H5O3 is 1.4 *10-4.) a. What is the pH of the buffer? b. What is the resulting pH if 10.0 mL of 1.00 M hydrochloric acid is added to 0.500 L of the buffer solution?

A lactic acid/lactate ion buffer solution contains 0.15 M HC3H5O3 and 0.82 M C3H5O3?, respectively. The Ka value of lactic acid is 1.4×10?4.
