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

At 100^oC the K_w of water is 55 times its value at 25^oC. What will be the pH of neutral solution? (log 55 = 1.74)
