Lactic acid (CH 3 CHOHCO 2 H) is found in sour milk, in sauerkraut, and in muscles

Question:

Lactic acid (CH₃CHOHCO₂H) is found in sour milk, in sauerkraut, and in muscles after activity. (K_a for lactic acid = 1.4 × 10⁻⁴.)
(a) If 2.75 g of NaCH₃CHOHCO₂, sodium lactate, is added to 5.00 × 10² mL of 0.100 M lactic acid, what is the pH of the resulting buffer solution?
(b) Is the pH of the buffered solution lower or higher than the pH of the lactic acid solution?
