Sodium citrate is a salt form of citric acid where the hydrogen ions are replaced by sodium citrate chemical formula Na3C6H5O7. Saline-sodium citrate solutions with a pH around 7-8 are commonly used as anticoagulants. Sodium citrate usually appears as a white, odorless, crystalline powder with sodium citrate molar mass of 258.07 g/mol and density of 1.78 g/cm3. It has a mildly salty and tart taste. The anticoagulant properties of sodium citrate come from its ability to chelate calcium ions needed for blood clotting. It also helps maintain blood pH and osmotic pressure when combined with saline. Citrate has a variety of applications and uses.
