Dry ice is the solid form of carbon dioxide (CO2), a molecule consisting of a single carbon atom bonded to two oxygen atoms. Dry ice is colorless, non-flammable, with a sour zesty odor, and can lower the pH of a solution when dissolved in water, forming carbonic acid (H2CO3).
Post. Share. Dry ice is not flammable or explosive, but it exerts pressure as it changes from solid dry ice to gaseous carbon dioxide. If dry ice is placed in a seal container, there is a risk of the container rupturing or of the cap rifling off of the container when you open it.
