Carbon Dioxide Molecular Formula

Chemical or Molecular Formula for Carbon Dioxide

Carbon Dioxide
This is the space-filling molecular structure for carbon dioxide. Ben Mills

Carbon dioxide normally occurs as a colorless gas. In solid form it is called dry ice. The chemical or molecular formula for carbon dioxide is CO2. The central carbon atom is joined to two oxygen atoms by covalent double bonds. The chemical structure is centrosymmetric and linear, so carbon dioxide has no electric dipole.

Carbon dioxide is soluble in water, where it acts as a diprotic acid, first dissociating to form the bicarbonate ion and then carbonate.

A common misconception is that all dissolved carbon dioxide forms carbonic acid. Most dissolved carbon dioxide remains in molecular form.
