Question

Accumulation of lactic acid, a monobasic acid in tissues leads to pain a feeling of fatigue. In a 0.10M aqueous solution, lactic acid is 3.7% dissociated. The value of dissociation constant for the acid will be?​

Answer 1

Answer:

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, Ka, for this acid will be (a) 1.4 x 10-5  (b) 1.4 x 10-4 (c) 3.7 x 10-4  (d) 2.8 x 10-4
