Lactic Acid and Sodium Hydroxide

CH₃CHOHCOOH + NaOH → CH₃CHOHCOONa + H₂O

Tổng quan

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.

Ví dụ thực tế

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

Tầm quan trọng công nghiệp

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.
