Lactic Acid and Sodium Hydroxide

CH3CHOHCOOH + NaOH → CH3CHOHCOONa + H2O

Visão geral

Lactic acid, produced during anaerobic metabolism in muscles, reacts with sodium hydroxide to form sodium lactate and water. Lactic acid has a pKa of 3.86 and exists in L and D enantiomeric forms. L-lactic acid accumulation causes the burning sensation during intense exercise.

Exemplo do cotidiano

The muscle burn during intense exercise is caused by lactic acid accumulation. Sodium lactate is used in IV fluids (Ringer's lactate) for rehydration.

Importância industrial

O lactato de sódio é utilizado na conservação de alimentos, na solução de Ringer (soro IV), em cosméticos como humectante e como matéria-prima do ácido poliláctico (PLA), plástico biodegradável.
