Sodium Citrate Formula
Sodium Citrate Formula
Citrates (sodium salts of citric acid) are chemical compounds. Three different kinds of sodium salts of citric acid are trisodium citrate, monosodium citrate, and disodium citrate. The symbol E number 331 (E331) collectively refers to all three salt types. Its chemical formula, Na3C6H507, indicates a sodium salt of citrate produced following the alkalizing activity.
On the other hand, sodium citrate refers to a third type: trisodium citrate. Sodium Citrate Formula is an important substance in the pharmaceutical and food industries.
Citric acid, a naturally occurring organic acid in foods like citrus fruits, corn, and other things is salt in foods like sodium citrate. It comes in the form of white powder or colourless crystals. Most sodium citrate is sold as trisodium citrate dihydrate, a white, crystalline substance.
Sodium Citrate Structural Formula
When exposed to moist air, it transforms into a white, crystalline, or granular powder with a faint liquescent smell. The Sodium Citrate Formula decomposes when exposed to red heat. According to the Material safety data sheet, its melting point is 300 degrees Celsius. International Chemical Safety Cards, however, state that its melting point is higher than 300 °C. It is stable in dry air but becomes anhydrous when exposed to temperatures above 150 °C.
The Sodium Citrate Formula is water soluble in 1.3 parts and boiling water soluble in 0.6 parts. It is virtually insoluble in alcohol. According to material safety data sheets (MSDS) and International Chemical Safety Cards (ICSC), it dissolves in 29 grams per litre at a solubility of 42.5 grams/100 ml at 25 C.
Properties Of Sodium Citrate
When exposed to moist air, it becomes a white crystalline or granular powder that is mildly deliquescent. When it is exposed to red heat, it decomposes. The Sodium Citrate Formula melting point is 300 degrees Celsius, as stated in the Material safety data sheet. Yet, its melting point is greater than 300° C, according to International Chemical Safety Cards (ICSC). It is stable in dry air but becomes anhydrous when exposed to 150 °C.
The Sodium Citrate Formula is 1.3 parts water-soluble and 0.6 parts boiling water-soluble. It is almost completely insoluble in alcohol. Its solubility is 42.5 grams/100 ml at 25 C, according to International Chemical Safety Cards (ICSC) and material safety data sheets, which state that it dissolves in 29 grams per litre.
Applications in medicine
Raising the alkalinity can change the pH of the urine and blood. This property of sodium citrate is beneficial in avoiding kidney stones. It is also used to treat metabolic acidosis, a type of renal problem that affects some people. To treat excess acid in the stomach, sodium citrate acts as a buffer and a neutralising agent.
Sodium Citrate Formula is also used as a constituent to prevent whole-blood coagulation during blood sampling, hemodialysis, and haemofiltration. The reaction of sodium citrate with calcium prevents blood clotting. It crystallises as oxalate (crystals seen in oxalate blood), which is insoluble or bound in a non-ionized state.
Applications in industry
Utilising Sodium Citrate Formula as a flavouring agent and preservative helps prevent microbial contamination. It is used as an oil emulsifier in cheese production. As a buffering agent, it helps keep the pH level stable in cosmetics. Sodium Citrate Formula is used in soft drinks and refreshing drinks to reduce sourness and enhance flavour. Sodium Citrate Formula is found in dishwashing detergents, laundry detergents, and surface-active agents.
Sample Questions
- How does sodium citrate dissolve?
Despite its stability in dry air, it becomes anhydrous when exposed to 150 degrees Celsius. A proportion of 1.3 parts of the substance is water-soluble and a proportion of 0.6 parts is boiling water-soluble. It is almost completely insoluble in alcohol. Its solubility at 25° C is 29 grams/Litre and 42.5 grams/100ml according to International Chemical Safety Cards (ICSC).
