6. Lactic acid (CH,CH(OH)CO,H) builds up in muscles as a result of their use during aerobic activity.
a) Based on your knowledge of conj. base stability, which proton (H, or H,) is more acidic, and Why?
H 0:
H3C-C-C
?H-ö: :ö-H
Lactic Acid
b) If the pH of a 0.0376 M solution of lactic acid is 2.66, what is the K, and pK, for this weak acid?
As usual, start with an equation and an “ice" table to help guide your analysis!
