Frequently Asked Questions
What is the primary use of Sodium Citrate?
The primary industrial uses of Sodium Citrate span across multiple fields. It is heavily utilized as an anticoagulant in medical blood collection tubes, an acidity regulator and preservative in food and beverages, an alkalizing agent in pharmaceutical syrup formulations, and a buffering agent in chemical applications.
What is the molecular weight and chemical formula of Sodium Citrate?
The common chemical formula for Sodium Citrate (specifically Trisodium Citrate Dihydrate) is Na3C6H5O7·2H2O, and the anhydrous form is Na3C6H5O7. The molecular weight (or molar mass) for the dihydrate structure is approximately 294.10 g/mol.
Why is Sodium Citrate used as an anticoagulant in tubes?
Sodium Citrate acts as an effective anticoagulant by chelating calcium ions in the blood. By forming calcium citrate complexes, it effectively disrupts the coagulation cascade, preventing blood from clotting, which makes it indispensable for coagulation tests in blue-top sodium citrate tubes.
What are the common medical applications of Sodium Citrate syrup?
In medicine, Sodium Citrate syrup formulations are used as systemic alkalizers to treat metabolic acidosis and to make the urine less acidic. This aids in preventing kidney stones and alleviating symptoms of urinary tract infections.
What does Sodium Citrate taste like and is it safe?
Sodium Citrate has a characteristically tart, mildly salty, and sour taste, often referred to as sour salt. It is universally recognized as safe (GRAS) by global regulatory bodies when handled and consumed under food and pharmaceutical compliance standards.
What are the key physical properties of Sodium Citrate?
High-purity Sodium Citrate appears as free-flowing, white crystalline granules or an odorless crystalline powder. It is highly soluble in water, practically insoluble in alcohol, and displays excellent pH buffering properties.
How should Sodium Citrate bulk chemical packs be stored?
It should be stored in tightly sealed, original packaging (such as 25kg or 50kg bags) in a cool, dry, well-ventilated area away from moisture and direct heat to prevent any caking or material degradation.
