Six astronauts are still on the space station as part of a planned year-long stay in space, the longest tour of duty in the station's 15-year history.
The molecular formula of citric acid is C 6 H 8 O 7. The chemical formula for citric acid is best shown by a diagram of its complete structural formula. This shows how the atoms are arranged in the molecule. Citric acid has three carboxyl or-COOH groups and is triprotic in nature.
Citric acid/potassium-sodium citrate can be used as a blood acid regulator. Synthesize solid materials from small molecules In materials science, the Citrate-gel method is a process similar to the sol-gel method, which is a method for producing solid materials from small molecules.
