Lactic Acid and Sodium Hydroxide

CH₃CHOHCOOH + NaOH → CH₃CHOHCOONa + H₂O

ภาพรวม

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.

ตัวอย่างในชีวิตประจำวัน

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

ความสำคัญทางอุตสาหกรรม

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.
