Citric acid also dissolves in absolute (anhydrous) ethanol (76 parts of citric acid per 100 parts of ethanol) at 15 °C. It decomposes with loss of carbon dioxide above about 175 °C. Citric acid is a triprotic acid , with pK a values, extrapolated to zero ionic strength, of 3.128, 4.761, and 6.396 at 25 °C. [ 21 ]
Potassium citrate (also known as tripotassium citrate) is a potassium salt of citric acid with the molecular formula K 3 C 6 H 5 O 7. It is a white, hygroscopic crystalline powder. It is odorless with a saline taste. It contains 38.28% potassium by mass. In the monohydrate form, it is highly hygroscopic and deliquescent.
Calcium citrate is an intermediate in the isolation of citric acid from the fungal fermentation process by which citric acid is produced industrially. [2] The citric acid in the broth solution is neutralized by limewater, precipitating insoluble calcium citrate. This is then filtered off from the rest of the broth and washed to give clean ...

Triethyl citrate is an ester of citric acid. It is a colorless, odorless liquid used as a food additive, emulsifier and solvent (E number E1505) [4] to stabilize foams, especially as whipping aid for egg white. [5] It is also used in pharmaceutical coatings and plastics. [6]
Ammonium ferric citrate (also known as ferric ammonium citrate or ammoniacal ferrous citrate) has the formula [NH 4]y[Fe x (C 6 H 4 O 7)].The iron in this compound is trivalent.All three carboxyl groups and the central hydroxyl group of citric acid are deprotonated.
Citrique Belge or Citric Belge, located in Tienen is a Belgian biotech company and one of the biggest producers of citric acid. The company has a production capacity of 120,000 tonnes of citric acid per year. [1] In 2020 it employed 340 people. [2]
Acid-citrate-dextrose or acid-citrate-dextrose solution (ACD; also known as anticoagulant-citrate-dextrose or anticoagulant-citrate-dextrose solution) is any solution of citric acid, sodium citrate, and dextrose in water. It is mainly used as an anticoagulant (in yellow top tubes) [1] to preserve blood specimens required for tissue typing.
