Accumulation of lactic acid \( \left(\mathrm{HC}_{3} \mathrm{H}_{5} \mathrm{O}_{3}\right) \), a monobasic acid in tissues leads to pain and a feeling
D of fatigue. In a \( 0.10 \mathrm{M} \) aqueous solution, lactic acid is \( 3.7 \% \) dissociated. The value of dissociation constant,
W \( K_{a} \), for this acid will be
(a) \( 1.4 \times 10^{-5} \)
(b) \( 1.4 \times 10^{-4} \)
(c) \( 3.7 \times 10^{-4} \)
(d) \( 2.8 \times 10^{-4} \)
