Buy Citric Acid!

Citric acid is a great investment. It's many varied uses make it a valuable commodity. Citric acid is used as a preservative and can be used to sour food, especially in soft drinks. Citric acid has cleansing properties, and is used in home cleaners like detergent as well as in the industry. It can even dissolve rust from steel. As an acid, it can be used to lower the pH balance of fluids or pharmaceuticals. With so many reasons to buy citric acid, why not do so today!

Bonds

This molecule is capable of forming the following bonds with another molecule:

  • London Dispersion Bond - All molecules can form this bond
  • Dipole to Dipole Bond - Citric acid is polar, so it can bond with the opposite pole on another molecule
  • Hydrogen Bond - Molecule has both hydrogen and oxygen, which can form bonds with the hydrogen and               oxygen on the other molecule

Structure and Polarity

This is a three-dimensional image of how my atoms are arranged in space:


In the diagram, the red dots represent oxygen, the black dots carbon and the white dots hydrogen. I would draw arrows showing the polarity of the bonds, but with the way that picture is drawn it would be difficult. This Lewis structure makes it easier to see the polarity of the bonds:


The molecule is polar. This is because it is not symmetrical and one side has more unshared electron pairs, making that side more negative than the other side. If it was non-polar all sides of the molecule would have an even distribution of unshared electron pairs.  

Who Am I?

Hello. My name is Citric Acid, also known as C6H8O7. I consist of 21 atoms, with six carbons, eight hydrogens, and seven oxygens.
