Accumulation of lactic acid $\displaystyle \left(\mathrm{HC}_3 \mathrm{H}_5 \mathrm{O}_3\right)$, a monobasic acid in tissues leads to pain and a feeling of fatigue. In a $\displaystyle 0.10$ M aqueous solution, lactic acid is $\displaystyle 3.7 \%$ dissociates. The value of dissociation constant, Ka, for this acid will be :
Official answer
(4)
$\displaystyle 1.4 \times 10^{-4}$
