800 mL of a 2 M lactic acid buffer at pH=4.2 is mixed with 600 mL of a 1 M lactic acid buffer at pH=3.9. After the two buffer solutions are combined, 300 mL of 1.5 M sodium hydroxide is added to the buffer solution. What is the pH of the solution after the sodium hydroxide has been added? (lactic acid pKa = 3.86)
