Lactic Acid and Sodium Hydroxide

CH3CHOHCOOH + NaOH → CH3CHOHCOONa + H2O

Übersicht

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.

Alltägliches Beispiel

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

Industrielle Bedeutung

Sodium lactate is used in food preservation, in Ringer's lactate IV solution, in cosmetics as a moisturizer, and as a feedstock for polylactic acid (PLA) biodegradable plastics.
