Applications:
Food:
Sodium citrate is chiefly used as a food additive, usually for flavor or as a preservative. Sodium citrate is employed as a flavoring agent in certain varieties of club soda. It is also used as an acidity regulator.
Buffer:
As a conjugate base of a weak acid, citrate can perform as a buffering agent, resisting changes in pH. Sodium citrate is used to control acidity in some substances, such as gelatin desserts.
Medical uses:
It is used today in blood collection tubes and for the preservation of blood in blood banks. The citrate ion chelates calcium ions in the blood by forming calcium citrate complexes, disrupting the blood clotting mechanism.
Sodium citrate is used to relieve discomfort in urinary tract infections such as cystitis, to reduce the acidosis seen in distal renal tubular acidosis, and can also be used as an osmotic laxative.
It is used as an antacid, especially prior to anaesthesia for caesarian section to reduce the risks associated with the aspiration of gastric contents.
