Acidic Acid has two formulas: C3H4OH (COOH)3 and C6H8O7. As it can be observed, there are 6 molecules of carbon, 8 molecules of hydrogen, and 7 molecules of oxygen. All the bonds are covalent, which means that molecules share their electrons in order to fill the outer energy shell. The first formula is more helpful in determining the structure of citric acid. There are three oxygen and hydrogen bonds (HO) that link with carbons, along with three double bonds involving oxygen that connect with carbon as well. That leaves 4 hydrogen molecules that bond with carbon in single bonds.
