Question

Accumulation of lactic acid (HC₃H₅O₃), a monobasic acid in tissues leads to pain and a feeling of fatigue. In a 0.10 M aqueous solution, lactic acid is 3.7% dissociates. The value of dissociation constant, K_a, for this acid will be

1.4 $ \times $ 10^$-$5

1.4 $ \times $ 10^$-$4

3.7 $ \times $ 10^$-$4

2.8 $ \times $ 10^$-$4
