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).
Dry ice is also sometimes referred to as âcardiceâ or âcard iceâ. Dry ice is a solid form of carbon dioxide.Dry ice is used as a cooling agent. Because dry ice does not melt into a watery mess, but vanishes âinto thin airâ, many think that this convenience outweighs the expense. Dry ice, on average, costs roughly $.60 a pound.ry ice is used as a cooling agent.
