Question

Sapling Learning nacm leaming Mapdes During exercise when the body lacks an adequate supply of oxygen to support energy production, the te that is produced from the breakdown of glucosé is converted into lactate. High lactate levels can e of the lactate hydrolyzes to lactic acid. The dissociation of lactic acid to lactate is shown in the reaction below. Lactic acid has a pK, of 3.86. Lactic Acid Lactate A solution containing a mixture of lactic acid and lactate was found to have a pH of 4.24. Calculate the ratio of the lactate concentration to the lactic acid concentration in this solution Number lactate lactic acid 1.99 There is additional foedback View this feedback bottom divider bar bar again to hide the additional feedback on the Incorrect on the divider Clase Previous ive Up & View Solution p rry Aquwn O Next Explanation

Explanation / Answer

Henderson equation is

PH = PKa + log [lactate] / [lactic acid]

4.24 = 3.86 + log [lactate] / [lactic acid]

[lactate] / [lactic acid] = 2.398

ratio of lactate to lactic acid is 2.398.
